Customers review summary

The Transparent Labs BULK Black pre workout appeals to customers with a clinically dosed formula that delivers clean energy, focused drive, and strong pumps. Clinically dosed caffeine, citrulline, and beta alanine drive rapid onset, sustained stamina, and little post workout crash while many like the natural ingredient profile. A few customers note sour or gritty flavors and foaming when mixing, yet most say the performance gains outweigh taste issues.

Out of the 10 years I spent in the Army I've
Out of the 10 years I spent in the Army I've taken LOTS of pre workouts and I have enjoyed this probably the most out of all others. It's not a jittery needles poking you kind of feel but a more locked in and focused feeling. My workouts usually last between 2-3 hours and the steady energy stays consistent throughout the workout and even the rest of the day.

High stim but not too high. Enough citrulline to actually work. Tingles without feeling like an allergic reaction. Not going to be my daily driver, but the one I take Saturday mornings when I have time to go harder and heavier. This is probably the most well rounded pre I've tried so far without lacking or being overkill in any area. Will buy again.
