I am about 3/4 of the way through my cycle of sustanon 250. I haven't had any trouble with my injections until last week. I didn't have one of my needles so I borrowed one from a friend. It was a little bigger gauge and shorter than what I normally use. Could this be the reason that I am still a little sore? I can also feel like a lump where I injected. Is this normal? If not what should I do if anything?
