Mass gainer are a normal supplements for thoes people who are thin and have less body weight and want to gain weight in order to look good. But the artificial things harm our body. Muscle blaze is one such product that says that taking this as a suppliment will help you gain weight and will make you more stronger than before but such products are just fake, it has no effect on the body rather it may harm the body, these are just for fooling the public and as an option to gain more money. It does not have any effect on the body of the person. Not a good product.
