This may be a stupid question, but I've only pinned 4 times so far. 3 times in the front quads, and once in the upper portion of the gluteus muscle. The 3 quad Injections are still really sore from last week. (Tren ace). But the glute Injection was painless and if I try I can't even find the spot I injected a couple hours ago. Not sore at all...did I do it wrong???!!! Thanks
