im getting worried that maybe im not hitting the muscle when im injcting. ive been injecting in my right and left glutes. i use 1.5 inch needles. i do the upper right area for the right side and the upper left area for the left side. im worried that i might not be hitting muscle as i have a fairly big butt. is there suppossed to be a seperate pinch once you hit muscle after the initial pinch when you pirece the skin? let me know what you think
