This is a fake product. All optimum nutrition supplements have a holographic seal which indicates the purity of the product and this product is absolutely fake. Believe me guys don’t buy it I also ignored other people reviews and now I got a fake product. Amazon sells duplicate optimum products. Don’t waste your money on this product go to authorized dealers of optimum nutrition or visit their site on the US site of the optimum Nutrition. You can buy genuine products from there I also bought a creatine from the authororized dealer and I am satisfied with the results I gain half inch of biceps in 3 weeks original on creatine. So guys please don’t ignore this review although I just want to guide you but if you want to spend your money on fake products so that is your own wish but fake products can cause kidney failure and other problems.
