I've always injected in my quads. I'm one of those types that puts the needle in real slow, I'm just to nervous to just jab it in. Out of the 30 or 40 injections I've done so far, I've only had 2 bad experiences, where I almost puked or passed out. Tonight was one of those nights, I got all light headed, almost passed out and had to force myself not to puke. I think I hit a nerve and a vein on the way in, cause it hurt like a bitch, my leg twitched and I could feel the oil going in, and it bled like a bitch when I pulled the needle out. Usually I don't get a drop of blood, but this was a gusher. I think that's why I alost puked, seeing all the blood running down my leg, aghh!
Oh well, it happens, just part of the game. I will still be injecting my quads every time because is it the easiest and most comfortable place IMO.
