Does it feel 'crunchy' when the needle enters and then you feel it hit the muscle - at this point is there any pressure causing the needle to back out or stop going in? Or do you force it - doesn't hurt and that's a reason you go back
I'd suggest try using other sites - they'll be virgin muscles for the most part so I'd pin what I'm going to work that day - idk if I shoot and get pip I'll hit that muscle hard which I usually work the muscle I pin anyway...
