I would use quads, glutes and delts. Biceps and triceps are only for ester-free gear like suspension, winny, and liquid d-bol. Here's my recommendations on pin sizes:
I'm not sure why everyone likes to use big
pins. Here's my $0.02 worth on size and why.
Use a 20g or
18g to draw gear with. Suck a little air in
syringe then replace the pin with a
25g (of course remove air before you poke). Use a 1" for everywhere (quads, delts, bis. tris) and a 1-1/2" for glutes (unless you're one of those skinny guys w/no arse).
You dull a
needle poking through the septum in a vial. So, doing this will give you fresh pin for the poke. It takes a LONG time to draw gear through a
25g pin (very frustrating if you do). The
25g will make you inject SLOWER. You shouldn't be injecting faster than 1cc per minute. The
25g will help injections go slower and will cause less trauma at injection site.
