post # 95 in this thread mentions two that were presented as legitimate and were later found to be fake, with a source link/url and quote. But that was not my point. You read into my posts things that were not there. All I ever said was that there are places in china that produce fakes. nothing more, nothing less.
Presented by whom. Not a scientific journal. There are people producing fake anythings you could imagine. Science occasionally gets sucker punched, just as religion has its Jim Jones. I don't see why it is important to the discussion here.
