I have a feeling that sources have been calling those no lable blue and brown top 192aa's as made by the people at Gensci. They are trying to make the no labeled generics (that cause welts) more credible.
As far as I know, only legit Jintropins from china are 191aa, all the rest like fitropin, somatren, generic blue-tops, etc., are 192aa, though I know at least one source that swears his blue-tops are 191aa.
A version made by chemist(s) who once worked for jintropin are supposedly making them. Didn't really know how else to word it. Sorry for the confusion.
