PPL had their databases compromised and then lied about it. I also got bad product from them a while ago. Basically sold 20mg var, but actually had 9mg Oxandralone and about 4-5 of tbol. When compromise happen all customers started getting extortion emails.
Alibaba is like any seller, needs to be tested. The test in this thread so far I think are good enough for me. And their price is pretty good. I always test everything. For me any vendor is as good as the batch I test. I always continue to test. I am also happy to post results here.
