What's Inside Transparent Labs Stim-Free Pre-Workout

Pump and Blood Flow Matrix

• Citrulline Malate 2:1 — 8,000mg — at 8g, this is one of the highest citrulline malate doses in any mainstream pre-workout, stimulant-based or otherwise. The 2:1 ratio means two parts L-citrulline to one part malic acid by weight, delivering approximately 5.33g of pure L-citrulline per serving. Citrulline converts to arginine in the kidneys with far greater efficiency than supplemental arginine itself, driving sustained nitric oxide production that creates vasodilation, improved oxygen and nutrient delivery to working muscle, and the full, pumped muscle sensation during training. Malic acid independently participates in the Krebs cycle as an energy production intermediate. Clinical research consistently shows citrulline malate improves muscle endurance, reduces time to fatigue, and accelerates post-exercise recovery — all dose-dependent benefits, and 8g is at the top of the researched range.†

Endurance and Performance Matrix

• Beta-Alanine — 4,000mg — the full clinical dose for maximizing intramuscular carnosine saturation. Carnosine buffers hydrogen ion buildup during high-intensity exercise, directly extending the time before the burning muscle fatigue that forces set termination. At 4g daily, carnosine levels reach meaningful saturation within 2-4 weeks of consistent use. The tingling sensation (paresthesia) that many users feel from beta-alanine is normal and harmless — it is particularly noticeable at 4g versus the 1.6-3.2g doses found in most pre-workouts.†
• BetaPure Betaine Anhydrous — 2,500mg — BetaPure is the premium, identity-verified betaine form guaranteeing purity and potency. At 2,500mg — the research-validated dose — betaine has been shown over 6 weeks to improve bench press volume, support body composition, and enhance training capacity. It functions as an osmolyte drawing water into muscle cells for intramuscular volume and hydration, as a methyl donor supporting homocysteine metabolism, and as an internal creatine precursor.†
• Taurine — 1,300mg — an osmolyte and conditional amino acid that contributes to cellular hydration, calcium signaling for muscle contractions, antioxidant protection against exercise-induced oxidative stress, and endurance support. Taurine also has nootropic properties that complement the focus matrix, and in the absence of caffeine, it provides the osmolyte and cognitive support typically delivered by the caffeine-taurine combination in stimulant pre-workouts.†

Energy and Focus Matrix — Stimulant-Free

• L-Tyrosine — 1,000mg — the amino acid precursor to dopamine, norepinephrine, and adrenaline. Without caffeine driving CNS stimulation, L-Tyrosine becomes the primary driver of mental focus and motivation — replenishing the catecholamine substrate that the brain draws on under the demands of intense training. Research shows tyrosine supplementation meaningfully improves cognitive performance under physical stress, and at 1g it provides the dose used in the most-cited performance research.†
• elevATP (Ancient Peat + Apple Fruit Extract) — 150mg — elevATP is the unique ingredient that differentiates Stim-Free from simply being a Bulk formula without caffeine. While caffeine and other stimulants produce energy by CNS activation, elevATP works through a completely different mechanism — it stimulates the body's own endogenous production of ATP (adenosine triphosphate) at the cellular level. Ancient peat extract combined with apple skin polyphenols activates ATP synthesis pathways that increase intracellular energy availability. Published clinical research on elevATP has shown improvements in power output, muscle thickness, and exercise performance without CNS stimulation. This is the only genuinely non-stimulant ingredient in sports nutrition that directly addresses cellular energy production rather than just blocking adenosine receptors the way caffeine does.†
• Huperzine A (Huperzia serrata) — 100mcg — a potent acetylcholinesterase inhibitor that works by blocking the enzyme responsible for breaking down acetylcholine in the brain. By inhibiting acetylcholine breakdown, Huperzine A raises and extends acetylcholine levels — the neurotransmitter responsible for neuromuscular signaling, learning, memory, and cognitive focus. At 100mcg, it is dosed at the effective range used in cognitive research. Huperzine A is the most potent non-stimulant focus ingredient available in supplement form — without caffeine's CNS activation, it fills the focus role through direct cholinergic mechanism.†
• SenActiv (Panax notoginseng + Rosa roxburghii) — 50mg — the same patented adaptogenic complex found in Transparent Labs Bulk and Bulk Black. SenActiv is concentrated in notoginsenoside R1 from Tienchi Ginseng root, which supports muscle cell autophagy — the cellular "cleaning" process that removes damaged cellular components and accelerates recovery. Combined with ginsenoside-like molecules from Chestnut Rose fruit, SenActiv promotes faster recovery signaling at the cellular level so you can come back to subsequent sessions more ready to perform.†
• BioPerine (Black Pepper Extract, 95% Piperine) — 5mg — absorption enhancer that inhibits the metabolic enzymes responsible for breaking down other active ingredients. Improves bioavailability of all other ingredients in the formula.†

Electrolyte Support

• Sodium (Himalayan Pink Salt) — 150mg | Potassium (Potassium Chloride) — 100mg — electrolytes for hydration support and muscle contraction signaling during training. A practical inclusion that stim-free athletes — who are more likely to be training for longer sessions in the absence of stimulant-driven focus — particularly benefit from.†

Frequently Asked Questions About Transparent Labs Stim-Free Pre-Workout

1. Will I notice anything different without the caffeine? Is Stim-Free actually effective?
   Yes and yes. What you will not feel is the acute CNS stimulation — the jolt of wakefulness, heart rate increase, and heightened alertness that caffeine produces by blocking adenosine receptors. What you will feel is the full pump and blood flow effect from 8g citrulline malate, the endurance extension from 4g beta-alanine and 2.5g betaine, and a measurable improvement in mental focus from L-Tyrosine and Huperzine A. The elevATP addition provides a cellular energy mechanism that works independently of CNS stimulation. For athletes who train without caffeine — whether by choice, by sensitivity, or by training time — Stim-Free delivers all the non-stimulant performance benefits of a world-class pre-workout formula. It is not a watered-down compromise; it is a completely caffeine-free formula that still contains more clinically dosed active ingredients than most stimulant pre-workouts on the market.†
2. Who specifically should use Stim-Free over Bulk or Bulk Black?
   Four primary groups. Athletes who train in the evening and cannot take caffeine without disrupting sleep — Stim-Free gives you the full pre-workout performance matrix without the 5-6 hour caffeine half-life that disrupts sleep quality. People who are stimulant-sensitive or have cardiovascular conditions that make high-caffeine pre-workouts inappropriate. Athletes who are cycling off caffeine to reset tolerance — Stim-Free maintains full training performance during a stimulant break. And people who stack their own caffeine source (morning coffee, a separate caffeine capsule) and want to control that dose independently from their other pre-workout ingredients. Any of these fits? Stim-Free is the right product.†
3. What makes elevATP different from just skipping caffeine and using regular pre-workout ingredients?
   Most stim-free pre-workouts remove caffeine and add more pump ingredients — more citrulline, nitrates, or glycerol — which is a valid approach but addresses a different gap than energy. elevATP specifically addresses the energy production deficit that removing caffeine creates by working at the mitochondrial level to increase intracellular ATP availability. It is a clinically studied ingredient with published human research showing improvements in power output and strength performance — not a marketing addition. The combination of elevATP's cellular energy mechanism with Huperzine A's cholinergic focus support makes Transparent Labs Stim-Free one of the few stim-free pre-workouts that genuinely addresses both the energy and focus gaps that come with removing caffeine, rather than just being a pump-only formula.†
4. Can I combine Stim-Free with my morning coffee or a separate caffeine source?
   Yes — Stim-Free contains zero caffeine and zero stimulants, making it completely stackable with any external caffeine source. Many users take it this way: their own controlled caffeine dose from coffee or a caffeine capsule, combined with the full non-stimulant performance matrix in Stim-Free. This approach lets you control caffeine intake precisely and independently of your pre-workout stack — particularly useful for people who want 100-150mg of caffeine rather than the 200-300mg in typical stimulant pre-workouts, but still want clinical doses of citrulline, beta-alanine, betaine, and the other performance ingredients.†

How to Take Transparent Labs Stim-Free Pre-Workout

Mix 1 scoop with 12-16oz of cold water 20-30 minutes before training. For tolerance assessment on first use, start with half a scoop (half the beta-alanine at 4g can cause noticeable tingling — starting with a half scoop lets you gauge your personal response). Beta-alanine paresthesia (tingling) is normal and harmless at this dose and typically diminishes with consistent daily use. Can be used any time of day without sleep disruption concerns. Stacks cleanly with Transparent Labs Creatine HMB (no caffeine interference), Post Workout, and Whey Protein Isolate.†
