Yea man, just try a new site. I am like you and prefer to stick to just rotating butt cheeks but sometimes you need to switch it up. Personally I hate quads but delts are easy for me.
Update did my first inject in my thigh and people at work ask why I walk funny . Holy shit I've had a peg leg since Tuesday afternoon . Anxious to see how squat day goes today. #anythingforgainz
