I never understood why people use it. These products are so unnatural. It is to be expected that they contain harmful substances. Many athletes use them and do not look like real people. They become like cyborgs from computer games. And the life expectancy of such people is much less. Famous Russian bodybuilder Dynamite died at the age of 46. He was fond of the use of such protein mixtures. He was a popular TV presenter in my country, it is a pity that he left this world so early because of the use of poisonous mixtures.
