I believe in this product 100%. And I have used this product till the end of its container life. I have seen good, decent and reliable gains and muscle maintenance with it. I do not recommend this for users that are sensitive to taste. This product is “fermented” and has odor and a rancid taste when taken alone with water. However my beef is not with it’s taste just an FYI per this review. Go out and buy this product, it’s well worth the money and you will love its many uses with pre/intra/post workout. Mixes fine with other drinks can’t tell it’s taste, but be in for a sh*t taste if your drinking this by itself with water.
