WHAT'S INSIDE
Need to know
Natural caffeine from green tea, paired 1:2 with L-theanine — a steady, even lift that builds over hours instead of spiking and crashing.
A three-source electrolyte complex — Himalayan pink salt, sea salt and potassium chloride — moves water where it needs to go, so everything else works faster.
Alpha-GPC, L-tyrosine and Panax ginseng feed the neurotransmitters attention actually runs on: acetylcholine for memory, dopamine for drive.
The formula
Eight ingredients. Nothing to hide.
02
L-Theanine
Increases alpha brain wave activity, promoting a state of relaxed alertness.
03
Taurine
Regulates neurotransmitters, boosting alertness and reducing anxiety for enhanced cognitive function.
04
Vitamin B Stack
Aids neurotransmitter synthesis and maintains healthy nerve cells, promoting cognitive function and physical energy levels.
05
Alpha-GPC
A precursor to acetylcholine, a vital neurotransmitter involved in memory.
06
L-Tyrosine
Boosts dopamine production, aiding alertness, motivation, and drive.
07
Panax Ginseng
Boosts focus, fights fatigue, and supports cognitive function by regulating dopamine and norepinephrine.
08
Electrolyte Complex
Himalayan Pink Salt, Sea Salt and Potassium Chloride work together to support hydration and mineral balance.
THE DIFFERENCE
Crafted for peak performance.
We spent over a year perfecting the blend. Every ingredient earns its place, from selection down to dosage.

QUESTIONS
Asked and answered.
150mg of natural caffeine — about a strong cup and a half of coffee — paired with L-theanine so it lands smooth instead of jittery.
Most people feel lift-off in about 20 minutes, with steady focus for 4–6 hours and no crash on the way down.
