Hip injections are done into the ventrogluteal muscle also known as the medial glute. It's my favourite spot and I'm happy to run entire enan or cyp cycles just alternating sides. I've never had an uncomfortable shot there much less painful.
The hip is actually a better pace to go for absorption. Can't remember why. Just remember my instructors insisting we give all of our patinets shots in the hip. you pretty much bend your leg at the hip put your palm on your hip bone and make a V with your thumd and index finger and aim anywhere inside the V.
the only problem with shooting AAS there is the quality of the AAS. if it is pharmgrade then maybe but if it is UG and a new source then I would be a little more hesitent. if you get some bad shit it will hurt liek a mother fucker and you chances for your hip to go septic increase and thats a nasty infection.
