i am on my first cycle of sust250 and my second shot. the first one someone did it for me . i did this one myself. i am shooting in the glutes. the first one they did kinda high where it shows on this page. i did it lower more in the metty part of the glute. the shot i did did not seem to hurt as bad or as long as my first one. is it better to shot in the metty part of the glute or a little higher like it shows in th e piucture
