OK heres the problem....tomorrow in my pharmacology lab we are practicing giving injections in the delt. We are doing a 1 cc shot of saline solution. Well since tomorrow is Thursday it's also time for my test e and deca shot. My girlfriend is coming to visit and since my roommate isn't going to be around before my girl gets up here I'm going to have to do myself in the delt. Is there going to be a problem with injecting my juice in the same spot as the saline? Or is it good to go?
