Optimum nutrition is a best whey protein which contains 24gm protein 5.5g BCAAs 4gm glutamine and glutamic acid in one serving. In 5 lbs packing 74 servings are there and all 9 amino acids which are very important for our body. I used it in regular basis throughout the workout and the results are totally wonderful. I had use this whey protein not only for stirring it in water or milk but used it as making some sweets but healthy one like you can say barfee.flavour are very good and delicious . Results are totally good and if we talk about price it is in budget if we talking about the best one. Its price in market is 5 to 6000 thousands but it contains 74 servings so a beginner can use it for 2 months and a advanced can use it for a month. Its very good and best whey protein I had ever seen.
