It might be a shocking revelation for you, but it is true that nowadays, many bodybuilders are in search of natural nutrients for their muscle building. In order to meet their need, they are scouring the internet to have the best source of it, human breast milk.
There are many forums that link interested body builders to mothers selling their milk. In the ads, these men clearly explain that they use milk for health reasons. They do not mind explaining their preferences like in one instance a man said that he prefers creamy, sweet milk versus soy-like milk.
