When it comes to supps, I basically assume that they are a scam until there are several independent studies that confirm otherwise.

The primary reason for the existence of supplement companies is to make money; everything else comes second. After the deregulation of the industry, it is up to the end consumer to prove that a product does not work as claimed. Compounding the issue is that there are so many variables in human metabolism and people's lifestyles that concluding one way or another would require a large and expensive study. Who is going to pay for it?

I am not saying that all supp companies are completely crooked but I think a lot are.

(FWIW I don't really consider protein a supp - basically it's just food)

I think if one wants some magic in a bottle then it's time to look at aas, not the supp store...
