i am on about my fitht shot i dont know if i am not flexible or not but hitting my left glute is a workout in itself. i want more control and plus its a bitch trying to aspirate with my left hand. i am going to try thighs next time, i checked spot injections but those pictures are pretty vauge, its the outer quadrant and pin shoudl go in horizontal, Is there margin of error,or just try to get in into the vacinity and aspirate.
