i would like to hear why as well. I used test e and other than a lot of post injection pain, i have nothing to complain about. Sterility, oil quality was good, passed thru an insulin syringe fine!(i only did this twice lol) I heard on a source discussion site that biomex may be run by the same person as geneza oils, so i dunno.
it seems you think they are contaminated in some way?
Hopefully you are not badmouthing them just because they are relatively new to the game, there is too much BS hearsay floating around the net.
edit: I am using their test currently, and I think some of the pain i experienced was simply because it was my first time, now it just feels barely noticable. I forgot i injected yesterday when i was writing this
