Anyone have experience with bis, tris, pecs, or traps? I see the pics of these injections and I can't imagine injecting into bis, pecs, or traps. I could possibly hit tris, but just wanting to hear what you all have experienced as far as pain, difficulty, etc....
Also, do you inject yourself or do you have someone else do it?
