so today i had to inject my friend with 1 ml of test e in the delt and when i put it all the way in the delt flexed 3 times and i pulled it out quickly, alot of blood flowed out then. Im worried that i hit a nerve, he says he can move the delt but it burns at the injection site. Other sites arent really an option for the glute i cant find the ventrogluteal spot because of too much fat and the needle is too short. In 4 days i will be injecting him again in the other delt and idk im scared now to do it. And its not him that flexed it just a small part of the delt flexed.
