I'm on a sust 250 cycle. I'm in my second week and i'm doing 500 a week. (tueday 250, thurs 250). I've been injecting in quads with a 1-1/2 inch 23g pin. The pain I'm getting from theese shots really suck. I've heard sust can be a painful shot so i was kind of prepared for it. If i begin shooting my delts, will i get the same pain as i get in my quads? Should i use a different size pin for delts, and how far in should i go?
