Yes sir. With oil based AAS, the shots are usually a little more on the painful side. Over time, your body will get used to them, but especially early on, they can be awful. Best bet is to inject slowly and keep the needle stable. After a shot, I would suggest massaging the area a little. If you do a glute or quad shot, going for a light walk after will allow the blood to move around the muscle and help the shot "settle"
