LMFAO!! Where the fuck do you think PEDs come from how how they were ever conjured up to begin with?
A lot of ped's are designed specifically for their intended purpose. GH, HGH, Anadrol, Anavar, D-bol, Androgel, etc. I always thought Clen was a designer drug created as a ped. There are many ped's created for the sole purpose of bodybuilding.
