Ok i succesfully just put it into my shoulder for the first time but, it is a 27guage i am using and i tried to find the best place to inject it and i thought my shoulder was cause i felt there was less fat there. Ok i pushed it in and i'm pretty shor it just pirced my muscle cause it was sore at that point and i injected it took me like a minute or 2, to inject. my question is will that be potent enough and do the job thats all i can get is a 27guge.
