I don't know much about drugs or gear, I do however know that most bodybuilders are extremists. They go all out on training, posing, diet, tanning, hours of cardio, etc.. (I'm not limiting this to pros, think about guys you know you compete at local shows, generally they live the lifestyle).
These guys consider their selves athletes. And like most athletes they want to make sure everyone knows how hard they work, their genetic gifts aren't that elite but their work ethic is.
When you think about how competitive (and secretive) bodybuilding is at the elite levels there is no way these guys would be willing to give drugs the credit they deserve. Even Arnold said they were the finishing touch. No one wants steroids to get to much credit for the effort they put in.
Even if someone were honest most still wouldn't believe, figuring they'd have an ax to grind.
That said I'm surprised Titus hasn't told his weekly use yet, at this point he's got nothing to lose.
*Guys I'll write Craigers and let him now his bros on getbig want the truth to bodybuilding supplementation.
