THE PROBLEM

Problem 1
Fuel
99% of preworkouts are solely fueled by caffeine

Problem 2
Endurance & Strength
Lack of blood flow prevents muscles from getting the proper nutrients for endurance and strength

Problem 3
Blood Flow
Caffeine narrows blood vessels and restricts blood flow to your muscles

Problem 4
Recovery
Lack of blood flow can also result in increased muscle soreness and recovery
WHAT SEPARATES US FROM THE COMPETITION?
Let customers speak for us
from 178 reviewsI have tried so many pre workout products over the years. I never really liked the way caffeine affected me. It usually gives me a boost followed a plunge. The GrowMuscle pre almost instantly kicked in and seemed to ramp up with my workout. I am not aware of anything comparable.

Product is fine and works well but these pouches was a poor decision from the canisters they were in. You should also consider individual packets for traveling so the TSA doesn't have to test the powder every time we go thru airports.

Best preworkout I have had. It’s a plus that it is caffeine free!

This stuff on tap instantly. The five minutes it takes from the car to the workout floor, you are feel the pre workout at work!

I like the product very. I like the way it makes me feel. Please keep sending me this stuff because I love it.

great stuff absolutely great pump and great tasting as well

I have been taking it for more than 10 years! I start my day off with it!

I have been taking L-Arginine for years and am well satisfied with the benefits I believe is attributed to takeing it. I have good blood pressure and a small amount of blockage 11 yrs ago! Had an angiogram recently and the blockage has not gotten worse, may have improved. I started using L-Arginine after my first heart cath.

I love the heat it brings, I get instant blood flow allowing me to push sooner! I am on my 3rd month using it 3 times a week.

Both my husband and I use this every day. With the help of this product and a couple of supplements, we are able to control our blood pressure. We feel also that we have increased energy on it. I would highly recommend this to anyone!

Awesome product! Cant see my workouts without it! Perfectly compliments GroMuscle as a totallly complete pre workout without the caffeine jitters!

I have high blood pressure and this pre workout has a minimal effect compared to others. I don't have the crash or all day feeling jacked with this product. It can cause some niacin rush or flushing when you first take it, but this goes away quickly. Good product I will continue to use it.
