    Cant go wrong with this product

    I used this product together with BCAA's and before i realized it i gained 15 pounds of muscle in about two months, i strongly recommend pairing this with BCAA's for anyone trying to get over a plateau in their training. I train 7 days a week for about 3 to 4 hours on a bodybuilding regiment and i feel no soreness when taking this product.
