oh, and the syringes were 23 gauge, 1.5" and they went all the way in. often there would be blood after coming out and he/i never bothered to "aspirate" but it seemed to go fine and like i said earlier he gained 25 pounds, went up 50 in bench, etc., and only lost half of it post cycle. he did lose some sex drive causing girlfriend (me) to look elsehwhere, but no pain no gain...
