Our ingredients

Green Tea Extract

Green tea naturally includes EGCG and L‑theanine, which enhance metabolic activity, provide antioxidant effects, and help smooth out the jittery “spikes” common with anhydrous caffeine.

Infinergy™️ Di-caffeine Malate

Infinergy™️ is a slow release caffeine that allows for long lasting sustained energy, designed to reduce the dreaded jitters or crash common with traditional energy drinks, and even improves digestion. It is shown that Di-caffeine malate can have 2x lasting effects than traditional caffeine.

Lions Mane Mushroom Extract 8:1

Known as the “smart mushroom,” Lion’s Mane supports brain health by stimulating nerve growth factor (NGF), a key protein for learning and memory. Early clinical studies suggest it may improve focus, cognitive performance, and reduce feelings of stress and fatigue — helping you stay sharp when it matters most.

GeniusPure© Alpha-GPC

Alpha‑GPC crosses the blood–brain barrier and is metabolized into choline, boosting synthesis of acetylcholine, a neurotransmitter critical for learning and memory, also aiding in focus, concentration, and muscular control.

Citrulline

L-Citrulline boosts blood flow, increasing oxygen and nutrient delivery to working muscles. Research in endurance athletes shows it can delay fatigue — with cyclists demonstrating up to a 12% longer time to exhaustion compared to placebo.
