Can I use a 1 in 25g pin to shoot in my chest? and how bad will it hurt (omnadren 2500 1cc and deca 300 1cc) I want to shoot in a place I can see so I can asperate properly.
Why don't you go for the quad instead. Less awkward, and the pin can go deep in the muscle belly.
To anwser your question, yes you can shoot it in your chest. 2 ccs might be a bit much for 1 pec.
