This topic starting heating up a few years back after some ivy league soccer brat began having anxiety attacks the same week he started taking some trash he bought from a mom and pop supplement store that was marked "not for human consumption". Somehow the story gained traction and the FDA took notice to the number of supplement shops carrying SARMs along with an endless number of sites marketing toward athletes that were offering SARMs "for research purposes only". I'm sure it all started way before this though
