F-Tyranny Pre-Workout Ingredients

F-Tyranny launches direct-to-consumer Monday, October 20th in three flavors, each with its own artistic statement piece. Inside, you're getting 24.2 grams per scoop of clinical dosing backed by research-grade ingredients.

Here's what's inside each serving:

Pump and Performance Foundation

• L-Citrulline – 10,000mg

  F-Tyranny opens with a sledgehammer: 10 grams of L-citrulline. Not 6 grams. Not 8 grams. A full 10,000 milligrams of the most effective nitric oxide precursor available.

  While L-arginine gets metabolized before it can do much good (with roughly 40% destroyed by intestinal enzymes and another 10-15% extracted by the liver), citrulline bypasses these roadblocks entirely.^[1][2] Once absorbed, citrulline converts to arginine in the kidneys and other tissues, elevating plasma arginine more effectively than arginine supplementation itself!^[1]

  The result? Increased nitric oxide production, enhanced blood flow to working muscles, and pumps that don't quit when the set gets brutal. Research demonstrates citrulline supplementation improves oxygen uptake kinetics during high-intensity exercise and extends time to exhaustion during severe-intensity efforts—precisely when you need blood flow most.^[2]

  Most pre-workouts short-change citrulline at 6-8 grams. 'Merica Labz went bigger... because when you're fighting tyranny, half measures don't cut it. The 10-gram dose puts F-Tyranny in elite company, delivering the kind of vasodilation and endurance support that matches the aggressive energy profile.

• Beta-Alanine – 3,200mg

  Beta-Alanine delivers the clinical 3.2g dose that separates those who train hard from those who quit when it burns. This non-essential amino acid floods your muscles with carnosine, the intracellular buffer that neutralizes hydrogen ions during high-intensity work.^[3] When your muscles scream and lactic acid tries to shut you down, carnosine steps in to延ch metabolic acidosis and extend your capacity to produce force.^[4]

  The tingling sensation -- paresthesia -- is your signal that beta-alanine is working. Meta-analysis confirms this dosage range delivers significant ergogenic benefits for maximal intensity exercise lasting 4-10 minutes, with particular effectiveness when supplemented consistently for 4+ weeks.^[5] Inside F-Tyranny's loaded formula, beta-alanine synergizes with citrulline's pump mechanism and the stimulant complex to push performance when every other pre-workout would let you fail.

  

  Yes, you'll feel the tingles. That's not a side effect... that's confirmation you're about to go to war.

• Betaine Anhydrous – 2,500mg

  Betaine Anhydrous delivers the clinical 2.5 gram dose that supports strength, power output, and body composition when training gets serious.^[6-8] This organic osmolyte works multiple angles: it drives cellular hydration in muscle tissue while acting as a methyl donor to support creatine synthesis and protein metabolism.

  At its core, betaine functions as an osmolyte, accumulating in muscle cells under metabolic stress to maintain optimal hydration and cellular function.^[9] When cells swell with betaine, they signal protein synthesis pathways while inhibiting breakdown.^[6-8] This cellular volumization doesn't just protect proteins from stress-induced damage; it creates an anabolic environment where muscle growth thrives.

  Research in trained lifters shows betaine paired with resistance training significantly improves body composition, increasing lean mass while simultaneously reducing fat mass over 6-9 weeks.^[6,7] Studies demonstrate enhanced work capacity during high-volume training sessions, with greater improvements in bench press training volume compared to placebo.^[10] The performance benefits appear strongest during metabolically demanding protocols... exactly where F-Tyranny shines brightest.

  At 2.5 grams, you're getting the research-backed dose that translates science into serious gains.

Focus, Drive, and Cognitive Enhancement

• L-Tyrosine – 3,000mg

  Tyrosine for combatting tyranny!

  L-Tyrosine at 3 grams fuels mental resilience when your workout demands it most. As the direct precursor to dopamine and norepinephrine, tyrosine keeps your brain firing on all cylinders when stress tries to shut you down.^[11]

  

  Here's what makes this dose aggressive: when you're pushing through brutal sets under high caffeine and intense physical demand, your brain burns through catecholamines faster than it can resynthesize them. That's neurotransmitter depletion: the biological reason you lose focus mid-workout.^[12] Tyrosine reverses this by ramping up synthesis only in actively firing neurons, precisely when you need it.^[11]

  The research backs this up: tyrosine supplementation improves working memory, cognitive flexibility, and attention under physically and mentally demanding conditions, from military combat training to cold exposure to high-heat exercise.^[12][13] Even without overt stressors, tyrosine enhances performance on cognitively challenging tasks by preventing the catecholamine decline that comes with intense mental load.^[12]

  At 3 grams, F-Tyranny delivers a clinically effective dose that keeps your drive locked in when most pre-workouts would leave you mentally checked out. This isn't just "focus support"... it's ammunition for your neurotransmitter reserves when you're at war with the weights.

• Alpha-GPC 50% – 300mg

  Alpha-GPC delivers 150mg of active choline at a dose carefully calibrated for cognitive support without overwhelming the user. As a choline-containing phospholipid, alpha-GPC converts to phosphatidylcholine after ingestion, crossing the blood-brain barrier to boost acetylcholine synthesis.^[14] Acetylcholine is the neurotransmitter at the coalface of the mind-muscle connection, supporting both cognitive function and neuromuscular signaling.^[15]

  Recent research shows that alpha-GPC enhances selective attention and processing speed, with yield doses around 300-350mg demonstrating measurable cognitive improvements in healthy adults.^[15] The 150mg active choline yield from F-Tyranny's 300mg dose sits in the effective range while avoiding the higher doses typically reserved for clinical populations. This supports sharpened focus during training sessions without excessive cognitive stimulation. Alpha-GPC works synergistically with the huperzine A included in F-Tyranny, which prevents acetylcholine breakdown and extends the nootropic effects.^[16]

  

  Beyond cognitive support, alpha-GPC has demonstrated ergogenic effects on anaerobic performance, with studies showing improvements in peak power and mean power during high-intensity efforts.^[17] This makes it a strategic addition to an aggressive pre-workout formula targeting both mental and physical output.

• Toothed Clubmoss (Huperzia serrata) – 20mg (std. to 1% Huperzine A)

  Huperzine A is the focus-sharpening finish to F-Tyranny's cognitive stack. This alkaloid from toothed clubmoss works by inhibiting acetylcholinesterase, the enzyme that breaks down acetylcholine. By blocking this breakdown, huperzine A extends the effects of the Alpha-GPC already working to boost acetylcholine levels. More acetylcholine means better mind-muscle connection, sustained mental clarity, and locked-in focus throughout your session.^[18]

  What makes huperzine A different from other acetylcholinesterase inhibitors is its selectivity and potency. It's 900-fold more selective for acetylcholinesterase over butyrylcholinesterase, which helps minimize peripheral side effects while maximizing cognitive benefits.^[19] The result is sustained focus that doesn't crash -- just smooth, dialed-in concentration from first set to last.

  Research shows huperzine A significantly increases acetylcholine levels across multiple brain regions, with strong effects in the frontal and parietal cortex, which are areas critical for working memory and cognitive performance.^[20] At 200mcg from the 20mg standardized extract, F-Tyranny delivers an effective dose to keep you mentally sharp when fatigue tries to derail your training.

The Stimulant Trio: Big D Energy

This is where F-Tyranny earns its name. The caffeine stack is serious business.

• Caffeine Anhydrous – 350mg

  Caffeine anhydrous delivers 350mg of fast-acting central nervous system stimulation, working as an adenosine receptor antagonist to amplify energy, alertness, and power output.^[21] When caffeine blocks adenosine receptors in the brain, it prevents the normal inhibitory signals that promote drowsiness and fatigue. This triggers increased release of dopamine, norepinephrine, and other neurotransmitters that drive motivation, focus, and physical performance.^[21]

  

  The anhydrous form absorbs rapidly from the gastrointestinal tract, with peak plasma concentrations typically occurring 30-120 minutes post-ingestion.^[21] At this dose, you're getting serious CNS activation that enhances reaction time, vigilance, and the ability to sustain high-intensity effort when fatigue sets in.^[22]

• Caffeine Citrate – 200mg (yielding ~100mg caffeine)

  Caffeine citrate brings another 200mg to the formula, but here's the critical detail: caffeine citrate is roughly 50% caffeine by weight, meaning you're extracting approximately 100mg of additional active caffeine. This pushes F-Tyranny's total caffeine content to approximately 450mg per scoop -- serious territory for experienced stim users.

  The citrate form kicks in even faster than anhydrous due to its higher solubility and rapid absorption kinetics.^[23] This creates a strategic two-phase energy curve: caffeine citrate hits immediately for that explosive kickstart, while caffeine anhydrous maintains sustained energy throughout your training session. You get the best of both worlds: instant ignition with long-lasting fuel.

  At 450mg total, F-Tyranny sits firmly in high-stimulant pre-workout territory, enough to boost strength in most people (as studies start showing strength and power gains at 3-6mg/kg^[21]). If you're not a seasoned caffeine user, this dosage demands respect. Start with a half scoop to assess tolerance before committing to the full serving.

• Methylliberine 40% (Dynamine®) – 100mg (yielding 40mg)

  Dynamine® rounds out the energy stack with 40mg of active methylliberine, the smooth operator that amplifies everything without adding jitters or extra caffeine.

  This purine alkaloid is a caffeine metabolite that hits adenosine receptors and boosts dopamine transmission, but with a key difference: it delivers feel-good energy and enhanced mood without the cardiovascular spike.^[24] While caffeine jacks up your blood pressure, Dynamine keeps your vitals in check while cranking up motivation, concentration, and sustained energy.^[25]

  The magic happens in how it works with caffeine. Research shows Dynamine synergizes with caffeine to enhance the mood-boosting effects while smoothing out the rough edges: no crash, no anxiety spike, just clean, sustained drive.^[26] Studies confirm improvements in energy, concentration, and the ability to tolerate stress that last up to three hours post-dose.^[25]

  

  In F-Tyranny's high-stim environment, Dynamine serves as the performance enhancer that extends your caffeine's effects while keeping you locked in and motivated. It's the ingredient that makes 450mg total caffeine feel powerful instead of chaotic — exactly what you need when crushing personal records.

Blood Flow and Bioavailability Enhancers

• Pine Bark Extract (Pinus pinaster) – 250mg (std. to 95% proanthocyanidins)

  Pine bark extract delivers 237.5mg of active proanthocyanidins, which are powerful polyphenolic compounds that amplify nitric oxide production through multiple mechanisms. These proanthocyanidins activate endothelial nitric oxide synthase (eNOS), the enzyme responsible for generating nitric oxide in blood vessel walls.^[27] This direct eNOS activation creates immediate vasodilation, flooding working muscles with blood, oxygen, and nutrients when you need them most.

  Beyond direct NO synthesis, pine bark's antioxidant properties protect existing nitric oxide from degradation by reactive oxygen species, which are the free radicals that normally destroy NO before it can work.^[28] This dual-action approach (boosting production while preventing breakdown) maximizes the pump you're getting from the 10g citrulline base.

  The result is enhanced blood flow that doesn't just create skin-splitting pumps but also supports nutrient delivery, waste removal, and sustained muscular endurance when you're pushing through brutal training sessions.^[29]

• AstraGin® (Astragalus membranaceus & Panax notoginseng Root Extracts) – 50mg

  AstraGin® is the absorption enhancer that makes everything else in F-Tyranny hit harder. This patented blend of astragalus and panax notoginseng increases nutrient uptake in your intestines by supporting ATP production and enhancing transporter activity. When you're dumping 10 grams of citrulline and 3 grams of tyrosine into your system, you want your body to actually use it, and that's where AstraGin® earns its spot. It's working behind the scenes to maximize bioavailability, ensuring nothing gets wasted.

The Flavors and Artwork: Presidents vs. Tyrants

Here's where F-Tyranny gets interesting. Each flavor features historically-inspired label artwork that's... let's just say it's bold. First, here's what's available... then we explain the tubs:

• Dragonfruit Blueberry: Freedom Dropkick

  George Washington (or possibly Jefferson? There's some debate) delivering a flying dropkick to a North Korean dictator. Freedom drop-kicking oppression in the most American way possible.

• Lychee Peach: The Constitutional Beatdown

  Abraham Lincoln boxing a caricature of opposing bearish leaders. It's symbolic, it's hilarious, and it's absolutely going to start conversations at your gym.

• Strawberry Lemonade: Revolutionary Grappling

  Benjamin Franklin himself, wrestling with a certain Eastern European leader we've had to come to respect. Because nothing says "rebellion against authoritarianism" quite like one of America's founding fathers throwing down with modern-day strongmen.

'Merica Labz also mentioned there are hidden Easter eggs throughout the label artwork. They haven't revealed what they all are yet, so you'll want to grab a tub and start hunting. Consider it a treasure hunt for freedom.

Dosing and Recommendations

Let's be clear: F-Tyranny contains roughly 450 milligrams of caffeine per scoop. That's serious stimulant territory.

Start with half a scoop to assess your tolerance, especially if you're not a seasoned stim user or sensitive to caffeine. Even experienced users might want to ease into this one. The combination of fast-acting caffeine citrate with sustained-release anhydrous creates a powerful, long-lasting energy curve that can catch you off guard.

Mix one scoop (or half to start) with 8-12oz of water 20-30 minutes before training. Don't take this late in the day unless you're planning an all-nighter or enjoy staring at your ceiling at 2am.

Your organs work harder than Congress! 'Merica Labz Organ Defender delivers comprehensive support with NAC, Milk Thistle, Red Yeast Rice, and more. Keep your liver, heart, brain and eyes functioning at peak levels while you push your limits.

Who should use F-Tyranny?

• High-stim enthusiasts who know their tolerance
• Athletes looking for maximum pre-workout intensity
• Anyone who wants zero compromises in their training fuel
• Patriots who appreciate politically-charged supplement artwork

Who should skip it or scale back?

• Caffeine-sensitive individuals
• Anyone new to pre-workouts
• Those training later in the evening
• People with cardiovascular concerns (consult your doctor)
