Key Highlights

• Formula 21 is Secret Weapon’s single debut product: a 21-ingredient stimulant pre-workout that prioritizes combined performance, pumps, and extended, smooth energy through paraxanthine instead of traditional caffeine.
• The formula pairs a full 5 g daily dose of creatine with branded actives (PeakATP), moderate beta‑alanine, pump agents, and a layered nootropic/adaptogen section; some key ingredients are dosed at levels that favor balanced effects rather than maximal acute dosing.
• At $49.99 for 22 servings (Electric Berry Bliss), Formula 21 targets lifters and focused athletes who want a multi-faceted pre-workout with attention to cognitive support and longer-lasting stimulant effects; users should be mindful of stimulant sensitivity and the need to maintain daily creatine for full benefit.

Introduction

Secret Weapon arrived in the supplement marketplace with a deliberately narrow debut: one pre-workout, Formula 21. The move is strategic. Rather than launching a broad catalog, the brand concentrated resources on a single formulation that tries to hit multiple performance targets simultaneously—strength, pump, focus, and sustained energy. That ambition shows up in the label: 21 active ingredients spanning classic, evidence-backed components and newer additions aimed at smoother stimulant delivery and cognitive reinforcement.

This review breaks down what Formula 21 actually contains, how each ingredient contributes to training, where dosages sit relative to established efficacy ranges, and how the product stacks up against more familiar pre-workouts. The goal is practical: help you decide whether this newcomer suits your training goals, tolerance, and supplement budget.

What’s inside Formula 21 and why the ingredient mix matters

Formula 21 markets itself on breadth: it lists 21 active ingredients that cover the typical pre-workout pillars—energy, focus, pumps, and performance—plus daily-support creatine. Rather than relying on a single large stimulant dose, the formula layers compounds intended to interact and smooth one another’s effects.

Key label highlights:

• 5 g creatine monohydrate
• 400 mg Peak ATP (adenosine 5'-triphosphate disodium)
• 2 g beta‑alanine
• 3 g L‑citrulline
• 1 g L‑arginine
• 250 mg paraxanthine (Enfinity)
• 500 mg alpha‑GPC
• 1 g L‑tyrosine
• 250 mg lion’s mane
• Theobromine, theanine, reishi and other supporting extracts (amounts not always specified on the marketing copy)

This combination signals two priorities. First, a commitment to long-term muscle performance via daily creatine and Peak ATP, which target ATP availability and recovery. Second, an emphasis on cognitive and sensory performance—alpha‑GPC, tyrosine, lion’s mane and paraxanthine create a stimulant/nootropic blend intended to deliver sustained focus without the peak-and-crash many associate with pure caffeine hits.

The balance matters because the pre-workout market has polarized: some formulas push maximal short‑term energy through high caffeine and massive citrulline doses; others focus exclusively on pumps or nootropics. Formula 21 attempts to be a hybrid, offering meaningful doses in multiple categories rather than maximizing a single effect.

The performance backbone: creatine, PeakATP, and beta‑alanine explained

Three ingredients form the performance core of Formula 21: creatine monohydrate, PeakATP, and beta‑alanine. Each has a distinct role.

• Creatine monohydrate — 5 g
  • Role: Increases intramuscular phosphocreatine stores, supporting rapid ATP regeneration for high‑intensity efforts and resistance training.
  • Practical significance: 5 g is the standard daily maintenance dose used in research and practice. Including a full 5 g per serving means one scoop of Formula 21 delivers an effective daily creatine dose for users who take it every training day. If you only use the pre-workout on training days, additional daily creatine on rest days will maximize benefit.
  • Real-world example: Athletes who add 5 g creatine daily typically see strength and power gains over weeks, and improved training consistency.
• PeakATP (adenosine 5'-triphosphate disodium) — 400 mg
  • Role: Claimed to increase available extracellular ATP, which may enhance muscular power and recovery between bouts.
  • Practical significance: PeakATP is a trademarked, clinically studied ingredient often dosed between 150–400 mg. The 400 mg inclusion in Formula 21 is at the higher end of the tested range and targets immediate burst power and reduction of strength decline across sets.
  • Real-world example: Some strength athletes report better set-to-set recovery and slightly improved peak power when using PeakATP at effective doses.
• Beta‑alanine — 2 g
  • Role: Precursor to carnosine, which buffers hydrogen ions in working muscle and delays muscular fatigue during sustained, high‑intensity efforts.
  • Practical significance: Beta‑alanine is typically effective at cumulative daily intakes of around 3.2–6.4 g split across doses to manage paresthesia (tingling). A single 2 g serving will contribute meaningfully but sits below typical effective daily totals. Users taking Formula 21 only once per day will receive a solid contribution, but those seeking the full anti‑fatigue effect should either take multiple servings daily or supplement beta‑alanine separately to reach clinically tested daily amounts.
  • Side note: Beta‑alanine’s tingling effect is dose dependent; 2 g reduces the chance of pronounced paresthesia for sensitive users.

Together, these three ingredients support short-term outputs (PeakATP) and long-term adaptations (creatine), while beta‑alanine helps delay fatigue during repeated high-intensity efforts. This structure favors lifters and athletes who want both immediate and cumulative benefits.

Pumps and nitric oxide: citrulline and arginine dosing considerations

Pumps come from increased blood flow to working muscles, mediated by nitric oxide pathways. Formula 21 uses two straightforward donors: L‑citrulline and L‑arginine.

• L‑citrulline — 3 g
  • Mechanism: L‑citrulline converts to L‑arginine, elevating plasma arginine levels more reliably than oral arginine and supporting nitric oxide (NO) production.
  • Efficacy: Effective acute pump doses typically range from 3–8 g of pure citrulline or 6–8 g of citrulline malate (a 2:1 mix). A 3 g dose sits at the lower end but still offers some pump benefit, particularly when combined with arginine.
  • Practical effect: Expect mild-to-moderate vasodilation and improved muscle fullness, but not the profound pumps produced by higher citrulline doses.
• L‑arginine — 1 g
  • Mechanism: Direct substrate for nitric oxide synthase to produce NO.
  • Efficacy: Oral arginine often shows limited effectiveness at increasing plasma arginine compared to citrulline because arginine is subject to first-pass metabolism. A 1 g dose is modest and functions more as a supporting agent than a primary pump driver.
  • Combined impact: The citrulline-plus-arginine pairing provides multi-pathway NO support. The formula’s pump strategy emphasizes a balanced sensation over maximal vasodilation.

For users who prioritize the biggest possible pumps, higher citrulline or citrulline malate doses may be preferable. Formula 21’s approach favors moderate pump enhancement coupled with cognitive and energy benefits.

Paraxanthine (Enfinity): a modern stimulant choice

Paraxanthine sits at the center of what sets Formula 21 apart from many other stimulant pre‑workouts. Secret Weapon chose Enfinity paraxanthine (250 mg) as its primary stimulant rather than the ubiquitous caffeine.

• What paraxanthine is: Paraxanthine is a primary metabolite of caffeine produced in the body after caffeine ingestion. It acts as a central nervous system stimulant with a similar molecular footprint but different pharmacokinetics and subjective effects.
• Why a brand might choose paraxanthine:
  • Smoother onset: Anecdotal reports and emerging research suggest paraxanthine provides alertness and energy with fewer jittery peaks and less of the sharp “crash” associated with high-dose caffeine.
  • Novelty and tolerance: Because paraxanthine is not as widely consumed as caffeine, some users experience a different tolerance profile or subjective sensation.
• Clinical and practical considerations:
  • Dose and potency: A 250 mg dose of paraxanthine is substantial; while direct caffeine-equivalent comparisons are imperfect, users should expect meaningful stimulant effects. For many, 250 mg equates to a strong pre‑workout stimulant punch.
  • Safety and regulation: Paraxanthine is a metabolite of caffeine and currently used in supplements, but it is newer to mainstream formulations. Users with cardiovascular issues or stimulant sensitivity should treat paraxanthine with the same caution they apply to caffeine.
• Real-world example: A lifter who usually gets 200 mg caffeine from coffee might find paraxanthine at 250 mg provides comparable alertness with a longer, flatter energy curve, reducing mid-session anxiety or late-afternoon crashes.

Choosing paraxanthine signals Secret Weapon’s aim to deliver sustained, focused energy rather than a rapid, spiking buzz.

The nootropic and adaptogen layer: alpha‑GPC, tyrosine, lion’s mane, and more

Formula 21 invests heavily in cognitive support. That section includes alpha‑GPC, L‑tyrosine, lion’s mane, theanine, theobromine, and reishi. Each contributes differently to focus, stress resilience, and mood.

• Alpha‑GPC — 500 mg
  • Role: Alpha‑GPC supplies choline, a precursor for acetylcholine, a neurotransmitter tied to memory, muscle activation and neuromuscular signaling.
  • Efficacy: 300–600 mg of alpha‑GPC is a common, effective range for acute enhancement of power output and cognition. At 500 mg, Formula 21 positions itself well for improved sprint or lift execution and tighter mind-muscle connection.
• L‑tyrosine — 1 g
  • Role: Amino acid precursor to catecholamines (dopamine, norepinephrine). Takes on greater importance during stress or sleep deprivation.
  • Efficacy: Acute doses for cognitive support commonly range 500–2,000 mg. A 1 g dose is moderate and likely to help focus during high-pressure sets or prolonged sessions.
• Lion’s mane — 250 mg
  • Role: Medicinal mushroom with suggested nootropic benefits that support nerve growth factor (NGF) signalling and cognitive performance over time.
  • Efficacy: Dosing in supplements varies widely; 250 mg can provide an acute mood-supporting effect but longer-term use often yields more notable benefits.
• Theanine and theobromine
  • Theanine (commonly paired with caffeine) moderates stimulant side effects and supports calm focus. Theobromine, a mild stimulant found in cocoa, can augment energy and vasodilation.
  • Practical effect: Together with paraxanthine and alpha‑GPC, these milder compounds craft a layered stimulant profile that supports alertness without harsh edginess.
• Reishi (mushroom extract)
  • Role: Adaptogen supporting immune and stress modulation; not a direct performance enhancer but valuable for overall resilience and recovery.

This blend emphasizes sustained cognitive clarity, improved neuromuscular efficiency, and a controlled sympathetic drive that favors long, productive sessions rather than short, frantic bursts of adrenaline.

Dosing realism: which ingredients are at clinical levels and which are conservative

A key point when evaluating multi-ingredient pre-workouts is whether the brand prioritizes a high count of ingredients at modest doses or concentrates on a few fully dosed actives. Formula 21 blends both approaches.

Ingredients at or near common effective levels:

• Creatine monohydrate — 5 g (effective maintenance dose)
• PeakATP — 400 mg (within tested effective range)
• Alpha‑GPC — 500 mg (effective for cognitive and power benefits)
• Paraxanthine (Enfinity) — 250 mg (substantial stimulant dose)

Ingredients effective but conservative per serving:

• Beta‑alanine — 2 g (contributes meaningfully but below typical daily study amounts)
• L‑citrulline — 3 g (moderate; lower than many pump-focused products)
• L‑tyrosine — 1 g (moderate dose for acute benefit)
• Lion’s mane — 250 mg (typical but not high)

Components with unspecified amounts on marketing material:

• Theobromine, theanine, reishi and other botanical extracts sometimes appear on labels as part of blends, with exact amounts omitted in promotional copy. Where label transparency is limited, it’s harder to evaluate efficacy fully.

Practical takeaways:

• If you expect strong pumps as a primary effect, higher citrulline would be necessary.
• For beta‑alanine users seeking maximal buffering over weeks, supplementing additional beta‑alanine to reach about 3.2 g daily will produce fuller benefit.
• The formula’s strengths are immediate power, daily creatine support, and a smoother stimulant/nootropic profile.

How Formula 21 compares to established pre-workouts

Comparing Formula 21 to market staples clarifies where it may fit in your rotation.

• Versus pump-focused pre-workouts (high citrulline, high arginine, large nitrates)
  • Formula 21 favors a balanced pump rather than an extreme vascular effect. If your priority is maximal muscle engorgement (bodybuilder pump sessions), a pump-centric product with 6–8 g citrulline will produce more intense results.
• Versus stimulant-heavy pre-workouts (high caffeine, D‑aspartic acid or DMAA-era stimulants)
  • Formula 21 offers a strong stimulant kick via paraxanthine but aims for smoother delivery. For users who want intense, rapid stimulation, high-caffeine formulas are often perceived as sharper; paraxanthine sits somewhere between smooth and potent.
• Versus nootropic-first pre-workouts (focus over pumps, cholinergics emphasized)
  • Formula 21 lands squarely in this territory. With 500 mg alpha‑GPC and cognitive mushrooms, it competes well against nootropic-focused competitors. The added creatine and PeakATP provide a performance advantage many nootropic-only products lack.
• Versus competitor multi-action products (e.g., products that combine creatine, citrulline, beta‑alanine and caffeine)
  • Formula 21 is similar in ambition but distinguishes itself by including paraxanthine and branded PeakATP, plus an explicit 5 g creatine inclusion per serving.

Price/performance context:

• At $49.99 for 22 servings, the per-serving cost is about $2.27. For a multi-faceted pre-workout that includes 5 g creatine and branded actives, that pricing is competitive. Pure high-dose pump or high-caffeine products might be cheaper per serving but lack some of Formula 21’s clinical actives.

Who should consider Formula 21 — user profiles and use cases

Formula 21 is designed for a broad athletic audience but suits specific profiles particularly well.

Ideal users:

• Strength athletes who want both immediate training performance and cumulative gain support. The inclusion of 5 g creatine makes Formula 21 attractive for lifters who prefer to get their daily creatine dose through their pre-workout.
• Athletes seeking focused, sustained energy rather than sharp stimulation. Paraxanthine delivers alertness that many describe as smoother, making Formual 21 useful for long training sessions, technical lifts, or daylong productivity when a crash would be problematic.
• Users who value cognitive clarity during training. Alpha‑GPC and nootropic mushrooms support concentration and neuromuscular coordination.

Edge cases where extra consideration is needed:

• Individuals who chase extreme pumps or vasodilation during every session. A dedicated pump formula with higher citrulline may be more appropriate.
• Stimulant-sensitive users. Although paraxanthine is described as smoother, 250 mg is a meaningful stimulant dose. People sensitive to caffeine equivalents should proceed cautiously.
• Those who don’t take supplements daily. Creatine’s benefits accrue with daily use, including rest days. If you only use the pre-workout sporadically, the creatine included in each scoop won’t fully achieve its long-term effect unless you maintain daily dosing.

Real-world scenarios:

• A competitive powerlifter who trains twice daily could rely on Formula 21 for pre-session performance and take an additional creatine dose on rest days or split the scoop across sessions to maintain beta‑alanine accumulation.
• An amateur athlete preparing for a long training day could use Formula 21 for balanced energy and focus without the jitter that high-caffeine stacks sometimes provoke.

Timing, stacking, and practical usage tips

Proper timing and stacking choices influence how you experience Formula 21.

Timing:

• Take Formula 21 20–40 minutes before training. Paraxanthine’s onset supports that window for peak effect during workouts.
• If you’re sensitive to stimulants, try a half-scoop test 30–60 minutes before intense sessions to gauge tolerance.

Stacking guidance:

• Daily creatine: If you only take Formula 21 on training days, add 5 g creatine on non-training days to preserve muscle creatine saturation for long-term gains.
• Beta‑alanine accumulation: To achieve target daily beta‑alanine levels (~3.2 g), supplement additional beta‑alanine on off days or split servings.
• Caffeine stacks: Avoid combining Formula 21 with high-caffeine sources the same day unless you’re confident in your stimulant tolerance. Paraxanthine will compound stimulant effects with caffeine.
• Pre‑workout pairings: If you want stronger pumps without losing Formula 21’s cognitive edge, add an extra citrulline dose or a nitric oxide booster on training days where pumps are prioritized.

Hydration and nutrition:

• Creatine draws water into muscle cells; maintain hydration, particularly during heavy training phases.
• Consume a source of carbs or a small meal pre-workout if performing prolonged or glycogen-demanding sessions. This supports high-intensity output and recovery.

Splitting doses:

• Some athletes split a serving across morning and pre-workout if they need cognitive focus earlier in the day and again for training. Keep in mind total stimulant exposure if you choose to split a full scoop.

Safety, side effects, and interactions

Supplements are tools with benefits and limitations. Formula 21 contains ingredients that require standard precautions.

Stimulant caution:

• Paraxanthine is an active stimulant; treat it like caffeine. Individuals with hypertension, heart arrhythmias, or prescribed stimulants should consult a healthcare provider before use.
• Avoid combining with other stimulants or monoamine oxidase inhibitors (MAOIs) unless cleared by a physician.

Beta‑alanine and paresthesia:

• Beta‑alanine can cause tingling sensations (paresthesia). At 2 g, this effect is reduced but possible. The sensation is harmless and dose-dependent.

Choline and cognitive actives:

• Alpha‑GPC is generally well-tolerated but can cause headaches or gastrointestinal discomfort in some users. Discontinue use if adverse effects appear.

Mushroom extracts and botanicals:

• Lion’s mane and reishi are well-tolerated by most, but allergic reactions are possible. Individuals with autoimmune diseases or those taking immunosuppressants should consult a physician.

Pregnancy, breastfeeding, and minors:

• Avoid use if pregnant or breastfeeding unless directed by a medical professional. Most stimulant-containing pre-workouts are not recommended for minors.

Drug interactions:

• Theobromine and paraxanthine may interact with stimulant medications. Users on antidepressants, blood thinners, or other prescription medications should check with a prescriber.

Quality and regulation:

• Dietary supplements are not regulated like pharmaceuticals. Look for third-party testing where possible and buy from reputable retailers to reduce risk of contamination or label inaccuracies.
• Branded ingredients such as PeakATP and Enfinity have manufacturing standards and research backing, but the overall product quality still depends on the company’s quality control.

Practical safety steps:

• Start with a half‑serving if you lack tolerance for stimulants.
• Track total stimulants across the day and avoid late-evening use if sleep is a concern.
• Maintain regular medical check-ups if using stimulants long-term.

Taste, mixability, and real-world user impressions

Flavor and mixability are subjective but influence consistent use.

• Flavor: Formula 21 launches in Electric Berry Bliss. Berry flavors generally mask acidic and fruity notes well; the expectation is a balanced, slightly sweet profile without overpowering bitterness.
• Mixability: Modern powdered pre-workouts typically dissolve easily in 8–12 ounces of water when shaken. If particulates remain, a blender or extra liquid will help.
• Sensory profile: With theobromine and paraxanthine included, users often report a smoother onset of stimulation and less of the classic caffeine “spike.” The alpha‑GPC and lion’s mane provide cognitive clarity that complements the stimulant feeling.

User impressions to expect:

• Immediate clarity without jitters for many users.
• Mild-to-moderate pumps rather than extreme vascularity.
• Noticeable power and focus increases, particularly for compound lifts and technical training.

Value proposition: cost vs. benefit

At $49.99 for 22 servings, Formula 21 positions itself in the mid-range of the pre-workout market. When evaluating value, consider both per-serving cost and which ingredients you value most.

• Per-serving cost: Approximately $2.27.
• What you get: 5 g creatine, branded PeakATP at 400 mg, paraxanthine at 250 mg, 500 mg alpha‑GPC, and a layered nootropic/mushroom blend.
• Cost comparison: Many basic pre-workouts price lower, but they may lack creatine, branded actives, or substantial nootropic blends. Formula 21 consolidates multiple categories into a single serving that covers both immediate performance and daily supplementation.

For someone who wants to streamline supplement intake—getting creatine, a performance aid (PeakATP), and a layered stimulant/nootropic in one tub—the value is strong. Users focused solely on pumps or those seeking minimalist stacks could find cheaper or more targeted alternatives.

Brand strategy and market position

Secret Weapon’s decision to launch with a single, feature-rich pre-workout is deliberate. New supplement companies often take two routes: broad catalogs or flagship product focus. By concentrating on a single flagship, Secret Weapon can:

• Build brand recognition around a distinct formula.
• Allocate resources to quality control, marketing, and formulation refinement.
• Differentiate by choosing paraxanthine and branded ingredients that other newcomers often omit.

Delivering a product that combines daily creatine with a layered nootropic and a smoother stimulant may appeal to consumers fatigued by high-caffeine formulas or crowded nitric-oxide battles.

Recommendations for specific users

• For strength and power athletes who want simplicity: Use one scoop pre-workout daily and add 5 g creatine on non-training days to maintain saturation if you skip the pre-workout on rest days.
• For athletes chasing maximal pumps: Supplement an additional 3 g L‑citrulline on workout days or opt for a pump-specific product on peak pump days.
• For stimulant-sensitive users: Begin with half a scoop and evaluate tolerance over a few sessions before moving to a full serving.
• For long-term cognitive support seekers: Consistent use of the alpha‑GPC and lion’s mane components may complement daily mental performance, but sustained benefits often take weeks.

How to evaluate whether Formula 21 is right for you

Consider four variables:

1. Your primary goal: strength and power? pump? clarity? Formula 21 is strongest for combined power and cognitive support.
2. Stimulant tolerance: If you tolerate caffeine well, paraxanthine will likely feel familiar but smoother. If you are sensitive, start small.
3. Creatine usage patterns: If you take creatine daily, the 5 g per scoop is convenient; if not, plan a separate creatine schedule.
4. Budget and priorities: The per-serving price is competitive for a multi-ingredient formula that includes branded actives. If you prefer single-ingredient optimization, you may split purchases between specialized supplements.

Practical buying and usage logistics

• Where to buy: Secret Weapon directs purchases to its own site. Buying directly from the brand often ensures authenticity, but reputable third-party retailers may also carry the product.
• Flavor options: Currently Electric Berry Bliss appears as the launch flavor. If you prefer broader flavor variety, check for future releases or contact the brand.
• Serving count and shelf life: 22 servings per tub. Store in a cool, dry place and follow expiration labeling for freshness.

FAQ

Q: Is Formula 21 safe to take every day? A: The formula contains daily-use ingredients like creatine, and many users will take one serving on training days. For full creatine and beta‑alanine benefits, daily consistency is recommended, which may require additional dosing on rest days. Treat the paraxanthine stimulant like caffeine—if you plan daily use, monitor sleep, blood pressure, and overall stimulant intake. Consult a healthcare professional if you have medical conditions or take medications.

Q: How does paraxanthine compare to caffeine? A: Paraxanthine is a primary metabolite of caffeine and delivers stimulant effects with a reportedly smoother onset and a reduced crash. A 250 mg dose is substantial and likely produces meaningful alertness. Users sensitive to stimulants should start with a smaller dose and assess response.

Q: Will the 5 g creatine in Formula 21 replace my creatine supplement? A: It can, provided you use Formula 21 every day. Creatine benefits rely on daily intake to maintain intramuscular saturation. If you only take the pre-workout on training days, add 5 g creatine on non-training days to preserve saturation.

Q: Are pumps from Formula 21 comparable to pump-specific supplements? A: Formula 21 provides moderate pumps via 3 g citrulline and 1 g arginine. Pump-specific products that deliver 6–8 g citrulline (or citrulline malate) will produce stronger vascular effects. Formula 21 emphasizes balanced performance and cognitive support over maximal pumps.

Q: Can I stack Formula 21 with other pre-workout or stimulant products? A: Avoid stacking with additional stimulants or high-caffeine products. Paraxanthine plus caffeine can compound heart rate and blood pressure effects. If combining products, keep total stimulant exposure conservative and consult a healthcare provider if you have concerns.

Q: Who should avoid Formula 21? A: Pregnant or breastfeeding individuals, minors, people with uncontrolled hypertension or cardiovascular disease, and those sensitive to stimulants should avoid or consult a physician prior to use.

Q: Does Formula 21 cause tingling from beta‑alanine? A: Beta‑alanine can cause a harmless tingling sensation. At 2 g, the sensation is milder than in higher single-dose formulas. If you are sensitive, start with a half dose.

Q: Is third-party testing available for Formula 21? A: Check the product page and packaging for third-party testing certifications or batch testing information. Third-party testing increases confidence in label accuracy.

Q: How should I measure my response to Formula 21? A: Track performance metrics such as lifted weight, rep quality, perceived focus, and recovery over several weeks. Note any sleep disturbances, heart palpitations, or digestive issues and adjust usage accordingly.

Q: What is the best time to take Formula 21? A: Take it 20–40 minutes before training. Adjust timing based on tolerance and onset experience. Avoid late-afternoon or evening doses if you are sensitive to stimulants.

Formula 21 stakes a clear claim as a hybrid pre-workout: one that supports acute power and sustained cognitive engagement while also covering daily creatine needs. Its distinguishing features—paraxanthine as a primary stimulant, PeakATP for power, and a layered nootropic suite—reflect an intent to provide a smoother, more controlled training experience. The trade-offs are modest pump dosing and a formula that favors balance across domains rather than extreme one-dimensional effects. For athletes and focused lifters seeking an all-in-one tub with a modern stimulant profile, Formula 21 deserves consideration—with the usual caveat to start conservatively and maintain awareness of total stimulant intake.
