Gets you cracked out in 10 minutes after dry scooping.
I been taking this line of pre workout for the longest of times. It has no artificial ingredients which is a major plus. After reading all the comments about the taste it makes me think people don't know what they are talking about. If you want a better tasting pre workout go buy something with artificial ingredients that wreck havoc on your gut system. I drink this like a big boy and dry scoop. Can't get any better than this, clean ingredients, 275mg's of clean caffeine (used to be 325) it doesn't get better than this.

Nasty and gritty
Terrible flavor. Was not at all as described. And there was a gross grit to the drink that would not go away no matter how much you shook it. Blender bottle, spoon stir, shaker, nothing helped. And there was an overwhelming sour taste that made stop think you just took a spoon full of citric acid.

Massive serving size for pre
The serving size is huge. If you don't mind mixing it with 20+ oz of water, it may not be a big deal for you. I mix half with about 8oz and it's still gritty and chalky. Wouldn't buy it again just based on that.

Watermelon peach best tasting
This one is the best tasting one. Not to sweet but it has a great taste. I've tried the black cherry and it was gross - I had to return cuz I couldn't drink it. So gave watermelon peach a try and so glad I did! It's good stuff? I'm 53yrs old on carnivore- this stuff really gives me a great kick to get through my workouts ?

Might need to triple scoop this one.
Minimal beta alanine itches. Autopilot effect comes too quickly.

Why transparent swears by stevia baffles me. People who are concerned with sUgAr, aren't drinking gallons of preworkout a day, so the "minimal" sugar in preworkout should not be a concern.

THIS WORKS
Tried several other "pre's" only to find BULK PRE-WORKOUT become my best choice. Not the best flavor, but what is more important for me is the results. I have not only great workouts, but can see my physique grow and improve.

  • Gorilla Mind
    Gorilla Mode Pre-Workout Formula – Blue Raspberry (1.75
    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.
