23guage
im a true green pea when it comes to all of this. brought on board by my boss who used to be a bodybuilder, so in that sense im lucky cause ive got someone who knows whats going on (plus reading all of the forum posts helps a lot too) but i gotta say something about this 23 guage pin shit regardless of how new i am.
i was using 21 guage 1" for shoulders 21 guage 1 1/2" glutes. took the first couple glute shots standing up. i tried sitting down then finally i figured out, if i lay flat on my stomach, that damn pin goes in easy as shit. so- ive got to assume going to 23 guage would be a breeze (simple math = it is a smaller needle, smaller pain) that fucking needle did go in fairly easy but it took so damn long for the test e to get into my arm im sold back on the 21. i dont like needles, i never have but good god id rather take a bigger needle for less time than that skinny little bastard
