also, as others have already stated, for the most part, they don't care about busting someone who's getting this stuff for personal use.
it's pretty pathetic when a LE agency is wasting time busting steroid users balls instead of trying to bust down on REAL drug dealers *Edited* . it's very very rare you ever hear of them busting steroid purchasers. that's not to say it doesn't happen of course, but expecting it to is like expecting to win the lottery.
also, though i don't know all the laws that well,
i don't think it would be too hard to get the case dropped with a good lawyer. i mean, you can use the justification that you self-administered HRT, go to a doc during pct while test levels are low to get a blood test to show your test levels are extremely low, and right there it's no longer abuse, but a necessity for good health and well being. now, i couldn't imagine any good lawyer having a problem convincing a jury of the health concerns of low test levels and the necessity of it for your well being.

i don't think they'd completely drop the entire case, but i'd say at worst you'd be looking at probation.
