Part of the reason they won't be accepted is due to RAMPANT irresponsible (and oftentimes dangerous) use by impatient and inexperienced trainees.
We can all read studies that show PEDs can and are used safely, but those are countered by the endless stream of jackassery that comes with novice steroid use. All one has to do is spend 10 minutes perusing the Anabolics section to see what I'm talking about.
Additionally, you won't hear stories about successful use. Guys that get blood panels before/during/after, practice responsible use and quietly grow aren't who we hear from. We hear from the idiots who think TRT is a legal cycle, idiots whose endocrine system is irreparably incapacitated from banging a gram of test/week for 6 months, idiots who beat the shyt out of someone in a fit of rage and blame "the juice".
The negative connotations are, at this point (IMHO), insurmountable.
