If you are gym going person then its necessary to take supplement to gain good healthy physics because daily protein is nessesery for our body and that can not be fulfill by only normal food you should have a balanced diet and supplement should also include in that balance diet but because of the fake supplement our body cannot get proper balanced diet and fake supplement is also harmfull for health. And forign supplements like ON, Isopure, SSN and many more are coming fake in the market. And ON is the brand where we find more fake product. As am gym going person I have try many supplement and majority of the fake which I got in Optimum Nutrition and very bad experience and wont recommend any one to buy it.
