When you go to the site, a reading about Tavin makes it sound as if the drug is one that is used when you are treating HIV (is that PEP?) rather than as being used as PrEP. For some reason I thought the PrEP drugs (Truvada) were actually the same as the HIV treatment drugs but I never knew for sure. So I guess they need to indicate that Tavin EM is also to be used as the PrEP drugs.
