I have the wrong pins for what I need until my new order comes, rookie move please advise. I have only 1" 23 gauge pins for tren ace and the propinator. With only having little to work with as far as length no pun intended (yeah thats what she said is funny) where should I inject? Obviously, shoulders but every other day they will be worn out and I have to use them to lift. With what I have where can I inject? I was thinking about injecting in two different areas of my shoulders giving me four sites but unsure.
