if you could "source" who's doing PEDS then they'd probably already be busted. I've seen dealers come in & out of MMA gyms and talk about what big name gyms they are headed to next, but that's whatever. It's a lot of hearsay as well, but I would go with the 60-70% are or have used PEDS at some point, but not so much for fight night advantages, I think that number is pretty low, but for recovery advantages during camp or just in general. Anavar is a popular one in MMA circles.
