Killer Stack Labs 0-HR Pre Workout

Its just right, not too much or too little lift after consuming.Feels good honestly, alot better for health than mentalHamster rubbish that O'Ds u on caffeine

Blue Raz tasted very peppery, also very difficult to scoop the powder out once it drops below a certain level but as an actual pre workout it's pretty good.

Best I’ve had for a Long time

Allot of power and allot for what you get! inside a cool bottle, keeps me going lifting heavy and getting the reps out.

When I wasn't feeling the gym this would give me the perfect pick up. I felt strong and concentrated in my session and from not wanting to train I went to having some of my best workouts. Great product!

Perhaps the best Pre-workout ive used after years of going to the gym. Everything in it you need for a beast of a workout and none of the dreaded “come down” effect. And what a container it comes in deffo gets people asking at the gym!!!

Brilliant. Gave me excellent focus and strength went through the roof. No come down after either. Tried a lot of the other big brands and this is far better. Definitely recommend!

Best pre workout by far!
