I bought retra from a vendor someone I don’t know recommended. The sender address was in the US and it came in a very nice box with vials that need reconstituting. But now I’m very nervous about using it. The attached is a certificate on the website but I guess anyone can falsify that. I don’t see anywhere that they tested for contamination? How do people send these things for testing? What I don’t understand is if you send a vial to test, then you can’t use that vial any longer. Can someone opine if you think is legit or how can I get it tested
