I just shot 1/2cc tren mixed with a 1/2cc of b12 in my right delt. When I pulled the needle out, this lump appeared right away and some blood came out. It looks like a marble is under my skin. I used a 25gu, 1" pin like I always do and it was in the whole way, so I know it was deep enough. Any thoughts on this. The lump has went down some, but you can still see it.
One more thing, when I first went to stick the needle in, it felt funny, so I moved over a bit and stuck it in. Shouldn't have anything to do with it though.
