Hydroxychloroquine seems like a weird example to bring up now, since it's been completely debunked. https://www.fda.gov/drugs/drug-safety-and-availability/fda-c...
I've read a debunking of that as well, which was basically that the study uses poisonously high levels of HCQ (much higher than normal or required), and that it uses no zinc. Zinc is the actual virus killer, HCQ just lets in into the cell (it's a zinc ionophore).
Unfortunately, it means just "trusting a peer reviewed study" is even harder than it should be. You have to dig into the study to see if it even makes any sense which can be very difficult. And you have to follow the money, not "even" if the study says what you think it ought to say, but especially when it says what you want it to say.
Very disappointing when you go digging in.
