Every dose. Justified.

The gold standard pairing. L-Theanine smooths caffeine's edge, eliminating jitters while preserving every bit of the focus boost. Studied extensively for gaming-relevant cognitive tasks.

Crosses the blood-brain barrier. Shown to boost acetylcholine — the neurotransmitter directly involved in reaction time, memory, and sustained focus. Clinical studies use 300–600mg.

Precursor to dopamine and norepinephrine. Blunts the cognitive decline from stress and sleep deprivation — exactly what happens during long sessions. 200mg is the effective acute dose.

Neuroprotective mushroom extract linked to BDNF upregulation — brain-derived neurotrophic factor associated with learning speed and neuroplasticity. Long-game cognitive support.

Patented piperine extract proven to increase bioavailability of other nutrients by up to 20x. Not a filler — it makes everything else work harder.

The de facto standard for pump and endurance. Converts to arginine in the kidneys, boosting nitric oxide more effectively than arginine itself. 6g is the clinical dose from peer-reviewed studies — most products use 3g or hide the dose.

Buffers hydrogen ions in muscle tissue, delaying the burn that forces you to stop. The tingling is real, the effect is proven. 3.2g is the dose used in clinical trials — not 1.6g dressed up on a label.

Anhydrous form for immediate absorption and maximal intensity. 200mg hits the sweet spot between peak performance enhancement and avoidance of CNS overstimulation.

Osmolyte that draws water into muscle cells. Backed by multiple RCTs showing increased power output and rep volume. 2.5g matches the effective dose in the literature.

Shuttles long-chain fatty acids into mitochondria. Reduces exercise-induced muscle damage, speeds recovery between sets. The tartrate form has superior absorption kinetics.

Time-release coating staggers absorption over 6–8 hours. No spike, no crash — just consistent output that matches the duration of your day, not a single session.

Same cognitive-enhancing mechanism as Speedrun. In the Preset formula it works synergistically with the adaptogens to maintain mental clarity during extended stress and recovery periods.

The most clinically validated ashwagandha extract. KSM-66® has 22+ human RCTs. Reduces cortisol, supports recovery from training stress, and maintains testosterone in the normal range during high training volume. 500mg matches the effective dose.

Higher dose than Speedrun — in Preset the priority is sustained calm focus over sharp cognitive activation. 400mg promotes alpha brainwave activity without sedation.

Adaptogenic herb with the strongest clinical evidence for reducing mental fatigue. Multiple RCTs show improved cognitive performance and work capacity under stressful conditions — exactly what late-night sessions and back-to-back training days are.
