Max daily dose increased from 30 grams to 40 grams of ingredients. Formula updates based on the most recent literature and over 1 million orders & user feedback. Markedly increased energy, focus, drive, and stress resilience. Enhanced vasodilation, explosive power, and muscular endurance. Amplified pump and muscle volume. New S Tier flavor systems. Naturally colored. Less clumpy, less gritty, and improved mix-ability. Gorilla Mode is our turnkey stimulant-based pre-workout formulated for intense pumps, energy, performance and laser focus. With an absurd 40+ grams of potent active ingredients per max dose, this product is fully efficacious from virtually every angle. Included is a maximum efficacious dose of L-Citrulline (10g) alongside topped-out dosages of Hydroprime Glycerol, Betaine, Creatine, and Pink Himalayan Sea Salt. Together, these ingredients will saturate your muscles with blood and intracellular hydration for an intense pump, vascularity, and muscular fullness. This product also contains an efficacious 400 mg of caffeine per max dose as the literature suggests peak ergogenic benefits of caffeine are typically observed at higher dosages. Notably, the potent nootropic complex: (an unheard of 5000 mg L-Tyrosine), 800 mg Alpha-GPC, and 200 mcg Huperzine A, significantly augments the perceived effect from the stim hit, driving a massive dopamine and adrenergic cascade. This synergy will provide a distinct enhancement of focus, mental clarity, sharpness, stress resilience, explosive power, drive, and motivation. Additionally, stacked pre-workouts are notorious for bad taste, horrible mixing, and are generally tough to get down. Not Gorilla Mode. With the help of years' worth of user feedback and over 1 million orders placed of our previous formula, we’ve dialed the flavor systems to be S-Tier (the taste is phenomenal) while improving the mixability and grit substantially.

What are nootropics? 

Nootropics are substances that bolster cognitive function by altering levels of certain neurotransmitters, enzymes, or hormones in the brain. 

What is citrulline malate?

Citrulline malate is a precursor to nitric oxide, which increases blood flow to working muscles and promotes greater muscle pumps and heightened energy levels.

What is beta-alanine? 

Beta-alanine is the modified version of the amino acid alanine. The body converts beta-alanine into carnosine, which supports exercise performance and endurance. 

What is betaine? 

Betaine is a naturally occurring amino acid-like compound that supports exercise performance and endurance.
