Key Highlights

• Pre-workout formulas can produce modest short-term gains in strength, power and endurance—largely driven by caffeine—while several ingredients require daily use for measurable benefit.
• Beta-alanine and creatine improve performance only after consistent loading (weeks), whereas caffeine delivers immediate effects; choose products and doses consciously to match goals and training time.
• Safety depends on ingredient amounts, stimulant content and individual health; select batch-tested products, read labels closely, and avoid high-stimulant blends if you have heart issues, pregnancy or sensitivity to caffeine.

Introduction

Many people rely on a quick lift of energy to show up for a workout: early mornings, late shifts, or an afternoon slump make training feel optional. Pre-workout supplements promise the missing spark—more focus, energy and the ability to push harder in the gym. Behind the colorful tubs and slick marketing are dozens of ingredients, each with a distinct mechanism and evidence base. Some produce real, measurable improvements; others contribute little beyond a placebo effect. A practical understanding of how common ingredients operate, what benefits are realistic, and how to use them safely will help anyone decide whether a pre-workout makes sense—and if so, which one to choose.

The choices stretch from single-ingredient caffeine to complex proprietary blends that mix stimulants, amino acids, nootropics and herbal extracts. The critical questions for athletes and recreational lifters are straightforward: which ingredients work acutely, which require loading, how much should you take, and what risks should you watch for? The answers change how you buy, dose and time a supplement—and whether you’re better off with a cup of coffee.

How pre-workout supplements produce their effects: the main mechanisms

Pre-workout products aim to change immediate feelings and physical capacity through several distinct routes:

• Stimulate the central nervous system to increase alertness and lower perceived effort. Caffeine and stimulant-containing plant extracts (for example, guarana) do this reliably.
• Buffer metabolic byproducts that cause fatigue in intense work. Beta-alanine raises muscle carnosine, which helps neutralize hydrogen ions produced during high-intensity efforts.
• Replenish or augment short-term energy systems. Creatine increases rapid ATP resynthesis, helping recovery between intense sets.
• Improve muscle perfusion and oxygen delivery. Citrulline and arginine boost nitric oxide and dilate blood vessels, potentially aiding endurance and the “pump.”
• Support neurotransmitters or stress resilience. Nootropics such as theanine, rhodiola and ashwagandha are included to smooth cognitive function, motivation and recovery.

A single dose of a pre-workout often produces immediate changes—mainly from stimulants—while other components need to build up in the body to deliver meaningful gains. Understanding which ingredients act fast and which require sustained use clarifies expectations and informs timing.

Caffeine: the primary, evidence-backed active ingredient

Caffeine drives much of the acute benefit seen with pre-workout supplements. Multiple studies show that a single dose of caffeine before exercise improves performance across strength, power and endurance measures. Typical effects include:

• Strength increases around 7% with doses of 3–6 mg/kg body weight (for a 75 kg person this equals roughly 225–450 mg).
• Endurance improvements in the order of 10–20% in time-to-exhaustion or time-trial scenarios.
• Lower perceived effort and greater alertness during training sessions.

These benefits make caffeine a potent and predictable tool. When pre-workout blends are compared directly to the equivalent dose of isolated caffeine, they rarely outperform caffeine alone. For many users, that raises a practical question: why buy a multi-ingredient product when a strong coffee or a measured caffeine pill could yield similar immediate gains?

Two points matter when using caffeine effectively. First, the dose: 3–6 mg/kg is the range most consistently associated with performance improvements. Second, timing: caffeine peaks within 30–60 minutes when taken orally, which makes that window ideal for pre-exercise ingestion.

Real-world example: a club-level cyclist who used to struggle with late-afternoon rides started taking 200–300 mg of caffeine 45 minutes before interval sessions. Over several weeks she reported improved threshold power and a consistent reduction in perceived effort during hard intervals, matching the dose timing from trials.

Beta-alanine: buffering fatigue, but only after loading

Beta-alanine targets a different problem: intramuscular acid accumulation during high-intensity exercise. The compound increases muscle carnosine levels, and carnosine serves as a buffer against hydrogen ions produced during anaerobic metabolism. This buffering delays the onset of muscular fatigue and can improve performance in sustained high-intensity efforts, such as repeated sprints or sets taken to near failure.

Key practical points:

• Beta-alanine does not work from a single pre-workout dose. Benefits typically require daily intake for roughly 2–4 weeks to raise muscle carnosine sufficiently.
• When effective, beta-alanine can improve work capacity in efforts lasting about 30 seconds to several minutes, and help athletes maintain power across repeated high-intensity bouts.
• A common side effect is paresthesia—a transient tingling or prickling sensation in the skin—that peaks about 20–30 minutes after ingestion and resolves within an hour. This is harmless but can be uncomfortable. Dividing the daily dose or using sustained-release formulations reduces the itch.

Real-world example: a recreational CrossFit athlete began a daily beta-alanine regimen alongside his training calendar. After three weeks he noted less fade during consecutive AMRAP (as many rounds as possible) sessions and more consistent rep counts between early and late rounds of conditioning workouts.

Creatine: not an immediate pick-me-up but a proven strength booster

Creatine monohydrate is one of the most-studied supplements for strength and muscle. Its primary action is to replenish phosphocreatine stores in muscle, allowing faster ATP regeneration during very short, intense efforts. That helps during repeated sets of heavy lifting or repeated sprints.

Important application details:

• Creatine requires consistent use to saturate muscle stores; measurable benefits generally appear after around four weeks of regular supplementation. Loading protocols (e.g., 20 g/day for 5–7 days followed by a maintenance dose) speed saturation but are not required.
• Once stores are elevated, creatine reliably increases the total work performed in training, favoring long-term hypertrophy and strength gains when paired with resistance training.
• Taking creatine in a pre-workout does not provide acute benefit from a single serving; it contributes to gains only through regular dosing.

Real-world example: a weekend powerlifter who added 5 g of creatine daily to his regimen increased his training volume over eight weeks and achieved a measurable one-rep max increase, identical to outcomes expected from creatine trials.

Nitric oxide boosters: citrulline, arginine and the “pump”

Citrulline and arginine appear in many blends as nitric oxide (NO) precursors. Increased NO dilates blood vessels, improving blood flow to working muscles. This can enhance oxygen delivery, nutrient transport and the subjective “muscle pump” during resistance training.

Evidence and limitations:

• Citrulline is more reliably converted into arginine and then NO when taken orally than arginine itself, which is rapidly broken down in the gut and liver. Doses of citrulline malate in the range of 6–8 g have been used acutely in trials.
• Effects vary: some studies show improved high-intensity endurance or reduced fatigue, while others fail to find a performance benefit. The ergogenic effect appears modest and inconsistent.
• The visible muscle “pump” during resistance training may be partly real (increased blood volume) and partly transient and cosmetic; it does not necessarily translate to greater long-term strength gains unless it facilitates better training volume or intensity.

Real-world example: bodybuilders often report that citrulline-containing pre-workouts enhance the pump during hypertrophy sessions, which can improve motivation for longer sets and slightly greater training volume. However, competitive trainees who measured objective strength metrics found mixed results.

Amino acids and branched-chain amino acids (BCAAs): targeted roles

Pre-workout products commonly include amino acids such as leucine, taurine and BCAAs. Their roles differ:

• Leucine directly stimulates muscle protein synthesis through mTOR signaling, supporting hypertrophy when adequate total protein intake is present. It is most effective as part of a daily protein strategy, not as an immediate performance enhancer.
• Taurine may reduce exercise-induced muscle damage and soreness in some studies. It also plays roles in cell volume regulation and antioxidant function.
• BCAAs alone do not substitute for sufficient dietary protein. When total protein intake is adequate, the incremental benefit of BCAA supplementation is small.

A practical takeaway: amino acids in pre-workouts can complement training but do not replace a structured nutrition strategy focused on total daily protein and calories.

Nootropics and adaptogens: brain-focused ingredients

Manufacturers have increasingly added nootropics and adaptogens to pre-workout blends to target focus, stress response and perceived energy rather than pure muscular performance. Examples include theanine, rhodiola, ashwagandha and other plant extracts.

What to expect:

• Theanine, often paired with caffeine, smooths the stimulant effect, reducing jitteriness while maintaining alertness. This pairing can yield a calm focus that many users prefer to jittery stimulation.
• Rhodiola and ashwagandha have evidence supporting improved endurance and reduced stress or fatigue in some populations, though results are not universal and effects build over time for some adaptogens.
• Nootropics are useful for athletes who need concentration for technical sessions or sports requiring sustained attention. Their role in pure strength or power is secondary.

Real-world example: a tennis player used a low-caffeine pre-workout containing theanine and rhodiola before long practice sessions. She reported steadier concentration across multi-hour training and fewer post-session energy crashes compared with caffeine alone.

Fat-loss and thermogenic claims: what the evidence supports

Pre-workout formulas sometimes include ingredients marketed for fat burning—green tea extract, carnitine, capsaicin, or other thermogenic agents. These substances can increase fat oxidation acutely during and after exercise, but evidence that they produce sustained, clinically significant weight loss when used as a supplement is limited.

Key considerations:

• Acute increases in fat oxidation do not automatically translate into long-term fat loss. Total energy expenditure and dietary intake remain the main drivers of body composition change.
• Green tea extract and caffeine can modestly raise metabolic rate and fat oxidation, but the size of the effect is small and variable.
• Carnitine’s effectiveness for fat loss is equivocal; benefits are more likely when combined with exercise and in individuals with deficiencies or older adults.

Practical guidance: treat fat-burning claims as secondary. Use evidence-based strategies—calorie management and consistent training—for body composition goals. Consider supplementation only as a potential, modest adjunct.

Comparing pre-workout blends to coffee or single-ingredient supplements

Given that caffeine explains most acute benefits, many users ask whether a pre-workout mix offers anything beyond a measured dose of caffeine. Trials comparing pre-workouts with matched caffeine doses find little or no advantage from multi-ingredient products for immediate performance.

Decision points:

• Cost and simplicity favor coffee or caffeine pills for many users wishing for acute improvement. A measured dose of caffeine (3–6 mg/kg) can be inexpensive and effective.
• Multi-ingredient blends may add value if they contain evidence-based, chronic-use ingredients (creatine, beta-alanine) that you plan to take daily. Combining these into a single formula can simplify dosing compliance.
• Some users prefer flavored pre-workout powders for convenience and palatability; a psychological preference can improve adherence to consistent supplement use.

Real-world scenario: a university rowing team compared caffeine tablets with a commercial pre-workout. Acute ergometer tests favored caffeine-matched doses rather than the blend, but athletes who used the blend long-term and benefited from daily creatine reported better strength gains over months.

Timing and dosing: practical rules of thumb

Effective use of pre-workouts depends on timing relative to exercise and appropriate dosing.

Timing:

• For stimulants like caffeine and many nootropics, take 30–60 minutes before exercise. This aligns with absorption and peak plasma concentrations.
• Nitric oxide precursors like citrulline can also be taken 30–60 minutes before training for acute vasodilatory effects.
• Beta-alanine and creatine produce benefit through chronic loading and need not be timed precisely around training, though many users take them pre-workout for convenience.

Dosing guidelines:

• Caffeine: 3–6 mg/kg body weight. Lower doses may help sensitive individuals; higher doses increase risk of side effects without reliably greater returns.
• Beta-alanine: daily total doses commonly range from 3–6 g/day, accumulated over at least 2–4 weeks. Split doses reduce paresthesia.
• Creatine: 3–5 g/day maintenance after optional loading; expect benefits after several weeks.
• Citrulline (malate): 6–8 g for acute ergogenic protocols, though evidence is mixed.
• Always read labels for total caffeine per serving. Many commercial pre-workouts contain 200–400 mg per scoop, sometimes combined with other stimulants.

Practical example: a 75 kg recreational lifter aiming for acute performance can take 225–450 mg of caffeine 45 minutes before a session. If using a pre-workout powder that lists 300 mg caffeine per scoop, one scoop meets that target. If the product also contains creatine and beta-alanine, those ingredients should be considered as part of a longer-term regimen.

Side effects and contraindications: who should be cautious

Most pre-workout formulas are reasonably safe in the short term for healthy adults when used at recommended doses. However, risks increase with higher stimulant content, certain botanical extracts, underlying health conditions and interactions with medications.

Common side effects:

• Jitteriness, anxiety, and insomnia from stimulants—especially when taken late in the day.
• Gastrointestinal upset in sensitive individuals, driven by caffeine or other herbal components.
• Paresthesia (tingling or itchiness) from beta-alanine, usually transient and harmless.
• Elevated heart rate or blood pressure in stimulant-sensitive users.

Specific contraindications and concerns:

• People with cardiovascular disease, uncontrolled hypertension or arrhythmias should avoid high-stimulant formulas and consult a clinician before use. Ingredients such as p-synephrine (bitter orange) have been repeatedly implicated in adverse cardiac events, particularly when combined with caffeine.
• Pregnant and breastfeeding people should avoid high-caffeine products; effects of many herbal ingredients during pregnancy are understudied. Clinicians generally recommend limiting caffeine and avoiding complex supplement blends during pregnancy.
• Individuals with anxiety disorders or sleep disorders should choose low- or no-caffeine formulations and avoid training late at night with stimulants.
• People taking certain medications—monoamine oxidase inhibitors, some antidepressants, stimulants, or drugs affecting blood pressure—should check interactions with a prescriber or pharmacist.

Risk reduction:

• Start with a half dose to assess tolerance, especially for new products or if you are stimulant sensitive.
• Avoid stacking multiple caffeine sources (for example, coffee plus a pre-workout scoop). Track total daily caffeine from beverages and supplements.
• Choose batch-tested products to reduce the risk of contamination with banned substances for competitive athletes.

Real-world cautionary tale: an amateur athlete combined a high-dose pre-workout containing caffeine and p-synephrine with multiple energy drinks on competition day. He experienced palpitations and dizziness, and required emergency care. This scenario highlights the danger of cumulative stimulant intake and the need to read labels carefully.

Choosing a product: what to look for on the label

Shopping for pre-workouts requires more attention than picking a flavor. Ingredients, dosages and testing all matter.

Checklist:

• Transparent labeling: products that list exact amounts of all active ingredients are preferable to proprietary blends that hide doses.
• Evidence-based components: check for creatine, beta-alanine and caffeine at doses aligned with research. Avoid products loaded with large arrays of herbal extracts at unclear doses.
• Caffeine content per serving: know how much caffeine you’ll ingest and whether you need to halve the scoop.
• Third-party testing: look for batch testing or certification from reputable organizations (for example, NSF Certified for Sport or Informed-Sport) to reduce the risk of contaminants or banned substances.
• Avoid excessive stimulants: products promising extreme energy may include multiple stimulants that cumulatively produce unsafe effects.

Practical tip: many reputable brands publish full ingredient breakdowns and testing certificates online. If such information is hard to find, the product may be less trustworthy.

How to integrate supplements into a training program

Supplements do not replace structured training, nutrition and recovery. They are tools to be used strategically.

Integration strategies:

• Use caffeine selectively for sessions where acute alertness and power matter: heavy lifting days, interval training or technical sessions requiring focus. Avoid habitual daily use at high doses to limit tolerance buildup.
• Maintain creatine and beta-alanine daily if seeking their chronic benefits. Track them separately if your chosen pre-workout does not provide the full research-based doses.
• Reserve fat-burning or thermogenic supplements for phases when small boosts in metabolic rate could support a calorie deficit, but prioritize diet adjustments and consistent training.
• Monitor subjective responses—sleep quality, gastrointestinal symptoms, and mood—and adjust timing or dose accordingly.

Program example: an intermediate lifter might take creatine daily and beta-alanine for at least six weeks while using caffeine only before two key weekly training sessions to preserve sensitivity and reduce sleep disruption.

Real-world user profiles and recommended approaches

Different training goals and lifestyles demand different approaches. Below are simplified profiles with recommended strategies.

• Morning commuter who trains before work: a moderate-dose pre-workout containing 150–250 mg caffeine can wake the system without causing excessive jitteriness. Pair with a light carbohydrate snack if energy is low. Avoid large evening stimulant doses that compromise nighttime sleep.
• Evening exerciser who trains late: choose low- or stimulant-free pre-workouts. Nootropic blends with theanine or adaptogens can assist focus without causing insomnia. Alternatively, use caffeine earlier in the day and rely on nutrition and warm-up strategies for later sessions.
• Strength athlete focused on long-term gains: prioritize daily creatine and consider daily beta-alanine for repeated high-intensity efforts. Use caffeine selectively for heavy sessions.
• Recreational exerciser seeking convenience: a single multi-ingredient pre-workout can simplify routines, but verify that creatine and beta-alanine are present at efficacious doses if you expect long-term benefits. Otherwise, use caffeine alone for acute sessions and add creatine separately.
• Athlete in a drug-tested sport: select products with third-party certification and avoid proprietary blends with undisclosed dosages. Consult with team nutritionists when available.

Cost-benefit: when a pre-workout makes financial sense

Commercial pre-workout powders can be expensive relative to buying individual ingredients or using coffee. Consider cost-effectiveness:

• If the primary goal is immediate alertness and a small acute performance boost, caffeine tablets or brewed coffee are far cheaper.
• If you want chronic benefits from creatine and beta-alanine, purchasing those ingredients separately may reduce cost per effective dose while allowing more precise timing and dosage.
• Some athletes value convenience, flavor and ritual; for them, a flavored pre-workout powder is a reasonable expense that promotes adherence.

A small cost calculation: creatine monohydrate at 5 g/day and daily beta-alanine split doses may cost a few cents per day when purchased in bulk. Commercial pre-workout tubs that include both ingredients plus stimulants can cost multiples of that amount without delivering proportionally greater benefit.

Regulatory and quality considerations

Regulatory oversight of dietary supplements varies by jurisdiction, but in most markets supplements are not subject to the same pre-market approval as prescription drugs. That means manufacturers can bring products to market without proving efficacy; responsibility for safety and labeling accuracy often rests with the producer.

Quality safeguards:

• Third-party testing and certification reduce, but do not eliminate, the risk of mislabeling or contamination. Look for batch testing, NSF Certified for Sport, or Informed-Sport logos.
• Avoid manufacturers that employ proprietary blends to hide ingredient dosages. Transparency is a hallmark of reputable companies.
• Be wary of exaggerated claims, especially about dramatic fat loss, miraculous recovery or instant muscle gains. Real gains arise from training consistency and appropriate nutrition.

Competitive athletes, in particular, should be vigilant: contaminated supplements can trigger positive doping tests. When in doubt, consult a team nutritionist or governing body resources on permitted substances.

Side-effect management and troubleshooting

If side effects occur, adjust dosing strategies before abandoning supplementation.

Common fixes:

• Jitteriness or sleep problems: reduce dose, move intake earlier in the day, or switch to lower-caffeine or stimulant-free formulas.
• Gut upset: try taking the product with a small snack, reduce the dose, or change brands; some formulations use fillers or sugar alcohols that cause GI distress.
• Paresthesia from beta-alanine: split daily dose into smaller servings or use sustained-release beta-alanine to smooth the effect.
• Palpitations or dizziness: stop use immediately and consult a clinician, particularly if symptoms persist.

Document your response to a new product for several sessions, taking a conservative approach to increasing doses.

Practical alternatives to commercial pre-workouts

Not everyone needs a commercial pre-workout powder. Effective alternatives include:

• Brewed coffee or measured caffeine pills: transparent dose; inexpensive and effective for acute stimulation.
• Simple carbohydrate snacks: for long or glycogen-demanding sessions, a banana or toast with jam 30–60 minutes before training can supply usable fuel.
• Creatine and beta-alanine powders purchased separately: allow precise, research-based dosing and often reduce cost.
• Hydration and a proper warm-up: many “energy” issues stem from dehydration or inadequate activation of muscles and nervous system; dynamic warm-ups and caffeine-free strategies can be sufficient for moderate sessions.

These alternatives reduce exposure to unnecessary ingredients and control cost while delivering core benefits.

How to evaluate whether a pre-workout is working for you

Measure both objective and subjective outcomes over several weeks. Useful metrics include:

• Objective: increases in training volume (sets × reps × load), improvements in time trials or repeat sprints, one-rep max progress over months.
• Subjective: session RPE (rate of perceived exertion), perceived focus, ability to sustain intensity across a workout, and recovery markers like soreness and readiness for the next session.
• Sleep and mood: track whether the supplement impairs sleep or increases anxiety.

If a pre-workout produces immediate perceived benefits but no measurable training improvements over months, consider switching strategies. Conversely, small immediate gains that support consistent training can compound into real performance increases over time.

Final practical guidance

Choose clarity over hype. If you want acute stimulation for a hard session, a known dose of caffeine is an effective, low-cost option. If your aim is long-term gains in strength and repeated high-intensity work, prioritize daily creatine and consider beta-alanine for buffering fatigue. Use nontoxic nootropics or lower-stimulant blends when focus without jitter is needed. Pay attention to total stimulant intake, product transparency, and third-party testing. Match supplement choices to your training schedule and health profile; the best product is the one you can use consistently without adverse effects.

FAQ

Q: Do pre-workout supplements actually make me stronger? A: They can lead to modest short-term increases in strength and power, primarily driven by caffeine. For meaningful and sustained strength gains, use evidence-based chronic supplements like creatine and maintain a structured resistance training program and adequate nutrition.

Q: How much caffeine should I take before training? A: Research supports 3–6 mg of caffeine per kg of body weight (roughly 225–450 mg for a 75 kg person) for ergogenic benefits. Start at the lower end if you are sensitive, and avoid taking additional caffeine from other sources close to exercise.

Q: Will beta-alanine help me right away? A: No. Beta-alanine requires daily intake for about 2–4 weeks to raise muscle carnosine enough to reduce fatigue during high-intensity efforts. Expect tingling sensations early in the course; these are harmless and can be minimized by splitting doses.

Q: Is creatine effective in pre-workout powders? A: Creatine is effective but needs consistent dosing over weeks to saturate muscles. A single scoop of creatine-containing pre-workout before a session will not provide immediate performance improvement unless you already have saturated stores from prior supplementation.

Q: Are pre-workouts safe? A: Most are safe for healthy adults when used as directed for short periods. Risks increase with high stimulant loads, specific botanical stimulants like p-synephrine, underlying heart conditions, pregnancy and medication interactions. Always read labels, start with a reduced dose to assess tolerance, and consult a clinician when in doubt.

Q: Should I choose a pre-workout with many ingredients or stick to caffeine? A: If you want short-term stimulation, measured caffeine is cost-effective and reliable. Multi-ingredient formulas can be useful if they include daily-use ingredients like creatine and beta-alanine at research-supported doses and you prefer the convenience of a single product. Prioritize transparency of dosages and third-party batch testing.

Q: Can pre-workouts help with fat loss? A: Some ingredients raise fat oxidation acutely, but the net impact on long-term weight loss is small without calorie control and consistent exercise. Use fat-burning claims as a secondary benefit rather than the primary justification for a supplement.

Q: What if I experience tingling after a pre-workout? A: That tingling (paresthesia) is commonly caused by beta-alanine and is harmless. It typically lasts less than an hour. To reduce it, divide the daily dose into smaller portions or use sustained-release formulations.

Q: Are there banned substances or contamination risks? A: Yes, contamination and undisclosed ingredients are a real concern, especially for competitive athletes. Choose products with third-party certifications like NSF Certified for Sport or Informed-Sport and avoid proprietary blends that conceal ingredient amounts.

Q: Can I take pre-workout every day? A: You can take some pre-workouts daily, but chronic high-dose caffeine use can lead to tolerance, reduced effectiveness and sleep disruption. For ingredients intended for chronic benefit (creatine, beta-alanine), daily use is appropriate. Consider cycling stimulant-containing products or limiting use to key sessions to maintain sensitivity.

Q: Is a flavored pre-workout powder better than coffee? A: Flavored powders can be more palatable and may contain additional beneficial ingredients. Coffee provides a simple, inexpensive and transparent dose of caffeine. The choice depends on cost, convenience and whether you want the additional chronic-use components some powders provide.

Q: Who should avoid pre-workouts entirely? A: People with uncontrolled cardiovascular disease, those advised by a doctor to avoid stimulants, pregnant or breastfeeding individuals, and anyone with known sensitivity to ingredients found in a product should avoid pre-workouts unless cleared by a clinician.

Q: How long before a workout should I take a pre-workout? A: Take stimulant-containing pre-workouts about 30–60 minutes before exercise to align with absorption and peak effects. Ingredients intended for chronic loading (creatine, beta-alanine) do not require precise timing.

Q: Can pre-workouts improve focus? A: Yes. Caffeine and some nootropics, such as theanine, can improve alertness and cognitive function during workouts. Nootropics may also smooth the stimulant effect for better concentration without anxiety.

Q: If I use creatine and beta-alanine, do I still need a pre-workout? A: Not necessarily. Creatine and beta-alanine help long-term training capacity and recovery but do not replace the acute alertness produced by caffeine. You can take creatine and beta-alanine daily and use caffeine (from coffee or a pre-workout) selectively for immediate performance enhancement.
