Great Product! Would recommend this to anyone looking to gain significant muscle gains without any negative side effects! The first week i started to notice I felt healthier, libido was going crazy and was sleeping better. My muscles also felt tighter. After 2 weeks my bench had gone up 70 lbs and i had gained 4-5 lbs of muscle mass. By the time I finished the bottle I had gained a total of 10 lbs of muscle mass and my strength had gone up to a place it has never been before naturally. I've been off of this for 18 days now and have lost none of my gains! Incredible for a product that is a natural testosterone booster!
