Ye I think the pain might just b site trauma. I had my guy do it for me I cldnt seem to balls up an do it, only reason I did the legs was just because I've gone their self administered before, I'm going to be pinning tren eod in about 4 wks so Ima stick to the 2cc test in the rear.
As of right now I'm just putting alot of heat on my bum.
