Yep, this is undecanoate, which seems to be popular in Europe. From what I've read, some of these sides, if not all, are caused by the much larger dosages (4CC is common). if that is the case, I don't know why they don't simply put a max limit on each injection. You would just inject more often, which is probably better anyway imo.
I know a while back they were considering setting a US limit of 3CCs I believe.
