I know there is lots of threads on prop pain and such. Trust me I have read most of them. I have read that prop is just painful and some causes that are suggested are bad injections(moving needle, virgin muscle, not hitting muscle, high BA% factor or some type of non-sterile complication), but WTF causes the prop lumps? What's even more obscure, the lumps are worse on the right side injections(R upper glute and R delt). The lump or swelling goes from muscles origin point to insertion point. Can any one give me some insight on solving this problem or am I stuck with it? I am injecting 1cc/100mg prop eod.
