Key Highlights

• Sam Sulek’s presumed pre-workout prioritizes vasodilation (L-citrulline, agmatine), central nervous system stimulation (caffeine, theobromine), and proven performance aids (creatine, beta-alanine).
• Effective pre-workouts combine science-backed dosages, timing, and user-specific adjustments; ingredients interact and require careful consideration of tolerance, side effects, and testing status for competitive athletes.

Introduction

Sam Sulek has built a reputation as one of modern bodybuilding’s most imposing physiques and disciplined competitors. Observers and fans routinely dissect his training, diet, and supplement choices to understand how he sustains extreme intensity and recovery. While Sulek has not publicly released a definitive list of the exact pre-workout he uses, the patterns evident in his training, public statements, and common elite practices allow a reasoned reconstruction of what an optimal pre-workout for an athlete of his caliber would contain.

This piece reconstructs that hypothetical formula and expands it into a practical guide. It explains why certain ingredients are included, how they function together, appropriate dosages, timing strategies, safety considerations, and how to translate these choices into real-world decisions. Those seeking an evidence-informed, athlete-grade pre-workout—whether competitive or recreational—will find actionable information and context to tailor an approach that matches goals, tolerance, and testing needs.

Vasodilation: The Foundation for Pump and Nutrient Delivery

Vasodilation sits at the heart of many elite pre-workouts because increased blood flow delivers oxygen and substrates to working muscle while amplifying the “pump” that supports both performance and motivation. For a physique-focused athlete such as Sam Sulek, the visual and physiological benefits of enhanced perfusion are valuable during both heavy compound work and high-volume isolation sets.

L-Citrulline L-citrulline converts to L-arginine in the kidneys, which then drives nitric oxide synthesis. Nitric oxide relaxes smooth muscle in blood vessel walls, increasing diameter and flow. Effective, sustained increases in blood arginine are more reliably achieved by supplementing citrulline rather than arginine itself because citrulline avoids rapid pre-systemic metabolism.

Typical effective dosing: 6–8 grams of L-citrulline (or 8–10 grams of citrulline malate, which pairs citrulline with malic acid). For strength and hypertrophy sessions that emphasize extended time under tension, 6 grams of pure L-citrulline or 8 grams of citrulline malate taken 30–60 minutes before training is a practical starting point.

Agmatine Sulfate Agmatine derives from arginine and is proposed to prolong nitric oxide activity by inhibiting arginase, the enzyme that breaks down arginine. Users report stronger, longer-lasting pumps and a different subjective quality to the mind-muscle connection. Research is mixed and less extensive than for citrulline, but mechanistic plausibility and anecdotal reports have made agmatine common in advanced stacks.

Typical effective dosing: 500 mg–1 g. Athletes often pair agmatine with citrulline for complementary vasodilatory effects. Expect variability in response; some users notice amplified pumps while others see no change.

How vasodilators stack When citrulline and agmatine are combined with mild vasodilatory methylxanthines like theobromine, the pump effect becomes multi-mechanistic: citrulline increases substrate for NO production, agmatine preserves arginine, and theobromine offers peripheral dilation. This layered approach explains the robust “swoon” in many elite pre-workout formulations.

Central Nervous System Stimulants: Focus, Drive, and Smooth Energy

A pre-workout must prime the brain as much as the body. Elite athletes need intense concentration for technical lifts, consistent tempo for hypertrophy, and the will to push past acute discomfort. Achieving this requires stimulants that increase arousal without producing anxiety or excessive cardiovascular strain.

Caffeine Anhydrous Caffeine remains the single most validated ergogenic aid for both endurance and high-intensity efforts. Its mechanism is primarily adenosine receptor antagonism, which reduces perceived exertion, increases alertness, and can transiently enhance force production and power output.

Dosing guidance: 200–400 mg, depending on tolerance and body mass. Competitive athletes who undergo testing for stimulants should confirm allowed thresholds with their sport’s governing body. Users sensitive to stimulants should skew to lower doses or split dosing.

Theobromine Theobromine, a methylxanthine found in cacao, resembles caffeine chemically but acts more gently. It provides sustained stimulation with less jitters and supports peripheral vasodilation. Theobromine lengthens the subjective energy curve, reducing the sharp peaks and troughs sometimes associated with high-dose caffeine.

Typical dosing: 100–200 mg. When paired with caffeine, theobromine smooths out the energy profile and can enhance the pump when combined with vasodilators.

Balancing potency and tolerance High-performing athletes often use moderate caffeine doses and layer milder stimulants to maintain focus without disrupting sleep or provoking anxiety. Periodic stimulant cycling—reducing or pausing stimulant use for several weeks—preserves sensitivity and limits tolerance buildup.

Performance Enhancers: ATP Support, Buffering, and Repeated Sprint Capacity

Beyond blood flow and alertness, a pre-workout should support the metabolic demands of the session. Two staples fulfill this requirement reliably: creatine and beta-alanine.

Creatine Monohydrate Creatine increases intramuscular phosphocreatine reserves, accelerating the regeneration of adenosine triphosphate (ATP) during short, high-intensity efforts. Benefits include higher peak power, increased training volume, and improved recovery between sets. Effects are best when muscle creatine stores are saturated, which requires either a loading phase (20 g/day for 5–7 days) or daily maintenance dosing of 3–5 g.

Dosing approach: 5 g daily is a simple, evidence-based maintenance dose. Taking creatine consistently, with or without a pre-workout, creates the cellular environment for repeated, intense training sessions—the core of sustained hypertrophy.

Beta-Alanine Beta-alanine increases intramuscular carnosine, a dipeptide that buffers hydrogen ions produced during high-intensity exercise. The buffering delays the onset of fatigue during efforts lasting roughly 30 seconds to several minutes—typical of many hypertrophy and metabolic conditioning sets.

Typical daily dosing: 3.2–6.4 g per day. Acute doses often produce paraesthesia (“tingling”), which is harmless but can be disconcerting. Splitting the daily dose into smaller amounts reduces tingling. Some athletes use sustained-release forms to mitigate sensation.

How these ingredients complement each other Creatine supports repeat power production and slightly increases lean mass over time, while beta-alanine improves the ability to sustain high-intensity efforts. When combined, athletes can maintain higher training volumes at higher intensities, speeding adaptation. Taking creatine daily and beta-alanine consistently over weeks maximizes these adaptations; pre-workout is mostly a convenient delivery vehicle for these compounds rather than a necessity for acute performance.

The Mind-Muscle Connection: Precision Over Placebo

Physical results hinge on more than supplements. The neurocognitive element—attentional focus, kinetic awareness, intent to contract—magnifies stimulus quality and muscle recruitment. When vasodilation and stimulation are aligned with precise technique, reps that would otherwise be half-hearted become training stimuli that provoke adaptation.

Practical techniques to enhance the mind-muscle connection:

• Pre-set intent: define specific targets for each set (e.g., tempo, peak contraction, contraction hold).
• Use warm-up sets as rehearsal for maximal form rather than mere muscle priming.
• Opt for visual and tactile cues (watching the contraction, using lighter weight to feel insertion points) during isolation movements.
• Prioritize compound movements early in the session when focus and systemic energy are highest.

A skilled athlete makes supplements an amplifier, not a substitute, for disciplined execution. The pump from citrulline or agmatine feels good but becomes meaningful only when it coincides with technique that targets hypertrophy or strength.

Timing, Dosage, and Practical Stacking

The impact of a pre-workout depends on when and how constituents are dosed. The same ingredients can produce different effects based on timing relative to the session and on whether the athlete has food in their stomach.

Timing window

• Stimulants such as caffeine: 30–60 minutes before training for peak central effects.
• Vasodilators: 30–60 minutes prior for optimal pump and flow.
• Creatine: works best as a daily habit; acute pre-workout ingestion is not required but common.
• Beta-alanine: requires days to weeks for carnosine accumulation—timing before a workout isn’t critical for acute effect.

Pre-workout on an empty stomach accelerates absorption and onset. Athletes who train early and cannot fast should aim for a modest snack 60–90 minutes prior, then take the pre-workout 30–45 minutes before lifting.

Sample pre-workout blueprint (athlete-grade, hypothetical)

• L-citrulline: 6 g
• Agmatine sulfate: 500 mg
• Caffeine anhydrous: 200–300 mg (adjust by tolerance)
• Theobromine: 100–150 mg
• Creatine monohydrate: 5 g
• Beta-alanine: 1.6–3.2 g (if used in a pre-workout serving; daily total should be 3.2–6.4 g)

Notes:

• Beta-alanine can be split between pre-workout and another serving to reach daily totals.
• Athletes sensitive to stimulants should halve the caffeine dose and increase theobromine slightly for smoother stimulation.
• If using citrulline malate, adjust the dose to roughly 8 g to match 6 g of free-form citrulline.

Cycling and progressive tolerance management Users often cycle stimulants two to four weeks on followed by one to two weeks off or reduce stimulant levels on non-training days. This preserves caffeine sensitivity and reduces sleep interference. Creatine and beta-alanine should be maintained continuously for best results.

Safety, Side Effects, and Contraindications

Every effective supplement has a risk-reward profile. Understanding side effects and who should avoid specific ingredients is crucial.

Caffeine-related concerns High caffeine doses can raise heart rate, increase blood pressure, precipitate anxiety, and disrupt sleep. Those with cardiovascular conditions, uncontrolled hypertension, or a history of arrhythmia should consult a clinician. Pregnant and breastfeeding women should limit caffeine intake.

Theobromine safety Theobromine is generally well-tolerated at supplement doses, though it can still contribute to nervous system stimulation. Theobromine’s vasodilatory effect may interact with prescription vasodilators or medications for erectile dysfunction—medical oversight is prudent.

Beta-alanine paraesthesia The tingling sensation from beta-alanine is harmless and short-lived. If distressing, split the daily dose into smaller amounts or use sustained-release formulations.

Creatine renal considerations Creatine is one of the most studied supplements and is safe for healthy individuals at standard doses. Individuals with pre-existing kidney disease should consult their physician. Routine hydration and awareness of gastrointestinal tolerance can prevent mild side effects such as bloating.

Agmatine evidence limitations Agmatine’s long-term safety profile and ergogenic efficacy are less extensively documented than creatine or caffeine. Short-term use at common doses seems tolerable, but clinical data are incomplete. Athletes competing under anti-doping rules should verify the legality of any ingredient; agmatine is not prohibited, but supplement contamination is always a risk.

Drug interactions and medical oversight Supplements can interact with prescription medications. Athletes on monoamine oxidase inhibitors (MAOIs), nitrates, blood pressure medications, antidepressants, or stimulants should double-check combinations with a physician. Those subject to drug testing must source supplements from third-party tested manufacturers to reduce contamination risk.

Reading Labels and Choosing a Product

A confident consumer reads ingredient labels and understands dose transparency, sourcing, and third-party testing. Marketing copy can obfuscate potency through proprietary blends and split dosing.

Dose transparency Avoid products that hide amounts behind “proprietary blends.” Look for supplements that list exact amounts per serving for all active ingredients. If creatine appears at microgram levels within a blend, the product is not delivering an effective dose.

Look for reputable testing Third-party testing—by NSF, Informed Choice, or USP—reduces the risk of undeclared substances. Competitive athletes should prioritize certified products that include a batch number and certificate of analysis.

Formulation balance A product that favors stimulants at the expense of vasodilators or includes negligible amounts of creatine/beta-alanine will deliver a qualitative “rush” without long-term training benefits. Conversely, low-stimulant formulas that emphasize pump agents can be ideal for evening workouts or stimulant-sensitive individuals.

Caffeine content and serving size Confirm caffeine per serving and check if the product recommends one serving or two. Many brands present a “one scoop” suggestion that is actually a fraction of the energetically marketed serving. If a label suggests multiple scoops to achieve an advertised effect, confirm total stimulant loads.

Cost vs. ingredient quality Higher price is not a guarantee of efficacy, but extreme bargains often cut effective doses or use cheap, questionable ingredients. Analyze the ingredient list for evidence-based doses rather than trusting brand narratives.

Translating the Hypothesis: Real-World Examples and Use Cases

Several commercial products align with the theoretical Sulek-style formula described. Rather than endorsing specific brands, the following examples illustrate common market approaches and how to match a product to goals.

High-stimulant, pump-focused products These often deliver 300–400 mg caffeine alongside 6–8 g citrulline and 3 g beta-alanine. Athletes seeking maximal arousal and a strong pump might favor these for morning sessions or heavy compound days. Sleep disruption risk means avoiding these in the afternoon.

Moderate-stimulant, smooth-energy formulas These feature 150–250 mg caffeine with theobromine and moderate citrulline (4–6 g). They suit athletes who tolerate stimulants poorly or who train later in the day. Theobromine softens the caffeine peak and sustains energy.

Stimulant-free pump stacks For evening workouts or stimulant-sensitive users, stimulant-free pre-workouts combine high citrulline (6–8 g), agmatine, and often adaptogens for focus (e.g., rhodiola). They prioritize blood flow and subjective focus without central activation.

DIY athlete-grade pre-workout Athletes who want precise dosing but avoid proprietary blends can mix measured powders:

• 6 g L-citrulline
• 500 mg agmatine sulfate
• 200 mg caffeine anhydrous (or a cup of coffee)
• 150 mg theobromine
• 5 g creatine monohydrate
• 1.6–3.2 g beta-alanine (to be split if reaching higher daily totals)

Measure with a scale and source powders from reputable suppliers. Label contents and practice good hygiene to minimize cross-contamination.

Case examples

• Strength athlete: Higher creatine consistency, moderate caffeine (200–300 mg), and 6 g citrulline for a balance of power and pump.
• Bodybuilder focusing on isolation and density: Higher citrulline (8 g), agmatine (1 g), and a mild stimulant profile (150 mg caffeine + 100 mg theobromine) to maximize pump quality without systemic tremor.
• Late-evening trainer: Stimulant-free citrulline/agmatine base plus adaptogens for focus, avoiding caffeine and theobromine entirely.

Special Considerations for Competitive Athletes and Testing

Supplements are not inherently prohibited, but athletes bound by anti-doping regulations have unique constraints.

Third-party certification Choose products with batch-specific certification from recognized testing bodies. Even permitted ingredients can pose a testing risk when products are contaminated with banned stimulants or SARMs.

Document everything Keep receipts and certificates, track lot numbers, and consult the relevant anti-doping body when unsure. Coaches and sports physicians are valuable resources for risk assessment.

Avoid novel or research chemicals Experimental stimulants and obscure peptides may promise performance but carry high contamination and sanction risk. Proven, well-established ingredients like caffeine, creatine, and beta-alanine present lower risk when sourced from certified manufacturers.

Practical Troubleshooting: When the Pre-Workout Isn’t Working

Many users fail to assess why a pre-workout feels ineffective. Common reasons include tolerance, poor match with training goals, timing mishaps, and underdosing.

Tolerance and habituation High daily caffeine intake outside training blunts pre-workout benefits. Reducing habitual caffeine and cycling stimulant use restores sensitivity.

Mismatch with training session A formula built for high-volume hypertrophy may disappoint on a maximal-strength focus day and vice versa. Match stimulant levels and vasodilator emphasis to the session’s demands.

Under-dosing or split dosing If label doses are low or split across servings, the acute effect may be diluted. Calculate total active amounts per recommended serving and adjust accordingly. For creatine and beta-alanine, remember that acute ingestion matters less than consistent dosing.

Gastrointestinal issues Some athletes experience nausea from pre-workout use, often due to high stimulant or citrulline concentrations on an empty stomach. Try smaller doses, take with a light carbohydrate snack, or use a different formulation.

Sleep disruption If pre-workout timing interferes with sleep, reduce stimulant load, shift training earlier, or switch to stimulant-free options. Poor sleep undermines training adaptation more than a small stimulant advantage helps acute session performance.

Ethical and Practical Final Notes on Performance Enhancement

Supplements complement training and nutrition but do not replace them. The athlete who consistently applies progressive overload, prioritizes recovery and nutrition, and structures training intelligently will get the most value from any pre-workout. Use supplements to enhance training quality, not to paper over inadequate programming or recovery.

A well-designed pre-workout should improve session intensity, sustain focus, and facilitate higher volume or heavier loads. For elite athletes, marginal gains matter, but they come from disciplined execution across multiple domains: sleep, diet, periodization, and supplementation that is well-sourced and properly dosed.

FAQ

Q: Is L-citrulline better than arginine for nitric oxide? A: Yes. Oral L-arginine is subject to extensive first-pass metabolism and less reliably raises systemic arginine levels. L-citrulline converts to arginine in the kidneys and yields more sustained increases in plasma arginine, making it the superior choice for supporting nitric oxide production in practice.

Q: How much caffeine should I take in a pre-workout? A: Effective ergogenic doses typically range from 200–400 mg depending on body mass and tolerance. Start at the lower end if you are sensitive, and avoid taking high doses within six hours of bedtime to prevent sleep disturbance.

Q: Can I mix creatine and caffeine? A: Yes. Current evidence does not indicate a practical negative interaction that undermines creatine’s efficacy. Daily creatine should be maintained regardless of acute pre-workout use, and many athletes mix both without issue.

Q: Is agmatine worth it? A: Agmatine shows mechanistic plausibility and positive anecdotal reports for pumps and subjective focus. However, clinical data are less extensive than for citrulline or creatine. It can be a useful adjunct for athletes seeking varied pump quality, provided they accept the limited research base.

Q: Will beta-alanine make me feel weird? A: Beta-alanine can cause a harmless tingling sensation (paresthesia). Splitting the total daily dose into smaller servings or using a sustained-release variant reduces this effect.

Q: How do I choose a pre-workout if I’m tested for banned substances? A: Select products with third-party certification (e.g., NSF Certified for Sport, Informed Sport). Keep batch certificates, consult your sport’s anti-doping authority, and avoid supplements that contain novel or poorly documented substances.

Q: Should I take pre-workout on non-training days? A: Stimulant-containing pre-workouts are unnecessary on rest days and can impede recovery or sleep. Creatine and beta-alanine should be maintained daily, while stimulant usage can be limited to training days or cycled.

Q: Can a pre-workout replace proper nutrition and sleep? A: No. Pre-workout supplements enhance acute performance but cannot compensate for inadequate energy intake, poor protein distribution, or insufficient recovery. Prioritize fundamentals and use supplements to refine, not replace, the training environment.

Q: Are there long-term risks to using stimulant-heavy pre-workouts? A: Prolonged high-dose stimulant use can affect sleep quality, cardiovascular strain, and anxiety levels. Periodic cycling and limiting stimulant exposure on non-training days reduce these risks. Individuals with medical conditions should consult a healthcare provider before regular use.

Q: How can I test whether a product contains the amounts claimed on the label? A: Purchase products from brands that provide third-party testing and batch-specific certificates of analysis. Independent testing through third-party labs is possible but costly; certification minimizes contamination and label accuracy concerns.

Q: What would a Sam Sulek-style pre-workout prioritize? A: A balanced formula featuring robust vasodilators (6–8 g citrulline), a preservation agent like agmatine, moderate-to-high caffeine (adjusted to tolerance), a smoothing methylxanthine (theobromine), and performance staples (5 g creatine, regular beta-alanine dosing) fits the profile of an elite, hypertrophy-focused athlete. Ultimately, training quality, nutrition, and recovery define success more than any single product.

Q: Can I make my own pre-workout mix? A: Yes. Athletes often prefer DIY mixes for full dose transparency and cost-effectiveness. Use precise scales for dosing, source ingredients from reputable suppliers, and store powders safely. Start with conservative doses and adjust based on response.

Q: How long before lifting should I take my pre-workout? A: Aim for 30–60 minutes before training for most stimulant and vasodilator ingredients. Creatine and beta-alanine benefit from chronic daily use, so their acute timing is less critical.

Q: Are there natural foods that can mimic pre-workout effects? A: Coffee provides caffeine; cocoa or dark chocolate contributes theobromine. Beetroot juice is a natural source of dietary nitrates and can enhance nitric oxide-mediated blood flow. These can provide a gentler, food-based alternative for some users, though precise dosing with foods is harder to control than with supplements.

Q: What should I avoid when choosing a pre-workout? A: Avoid products that hide dosages behind proprietary blends, contain a long list of exotic or poorly studied stimulants, or lack third-party testing. Overemphasis on “rush” ingredients with negligible evidence for performance benefits usually signals a marketing-focused product rather than a training-focused one.

Q: How do I measure success with a pre-workout? A: Track objective metrics such as training volume (sets × reps × weight), power output, perceived exertion, and subjective focus across sessions. If a pre-workout consistently improves these metrics without negatively affecting recovery or sleep, it is serving its purpose.

Q: Is it necessary to take the same pre-workout forever? A: No. Athletes rotate formulas, adjust dosages, and cycle stimulants to manage tolerance and align with training phases. Periodized supplementation—matching stimulant load and pump focus to competition or hypertrophy blocks—optimizes long-term progress.

Q: Can women use the same dosages as men? A: Dosage should reflect body mass and individual sensitivity. Many women tolerate similar regimens but often start with conservative stimulant doses and scale based on response. Creatine and beta-alanine dosing recommendations remain consistent across sexes when adjusted for body weight differences.

Q: Are there age limits for these supplements? A: Many ingredients are studied primarily in adults. Adolescents and younger athletes should consult pediatric or sports medicine specialists before initiating supplementation, especially with stimulants.

Q: How do I combine pre-workout with intra-workout nutrition? A: A well-hydrated athlete who consumes appropriate glycogen replenishment and protein across the day usually does not need complex intra-workout nutrition for standard resistance sessions. For long or glycogen-depleting sessions, a carbohydrate-electrolyte drink may support sustained performance.

Q: What’s the bottom line on replicating elite athlete supplementation? A: Elite-level results derive from consistent, progressive training, disciplined nutrition, recovery prioritization, and smart supplementation. A well-formulated pre-workout that uses evidence-backed doses and is compatible with the athlete’s health and competition rules can sharpen performance but does not replace fundamentals.
