NBA - Main

I don't think that Olympic testing is quite as thorough as it should be across all sports, so though they are likely much cleaner than the athletes in the major sports with the most money; I don't think they are as clean as something like cycling where the amount of testing and biological passport makes it next to impossible outside of a few specific circumstances/times (ie altitude training).

Lol. They all take something. Maybe not necessarily the gymnasts or whatever but any sport that requires otherworldly bulk and or mass then yeah.

Tons of guys take SARMs. I knew an entire college baseball team taking them, stuff like RAD 140. Also know a few AA baseball players that were taking them, they said everyone was. They're not illegal and a ton of places haven't caught up to banning them. You can order it to your house right now. They'll take it until it gets banned then they'll switch to a close analogue and keep going until they stop playing.

And before you go order them they have most if not all of the same negative effects normal roids do.
