So I hope I'm not talking past you, my perspective on the situation seems to somewhat oppose your intuition. Ivermectin is not a tightly kept secret. It has just been suppressed in the mainstream channels. Bret Weinstein has discussed this.

That website lists doctors who will hotline you a prescription. Maybe it's harder outside the US, but I know you can get off branded forms of it (perhaps those are worth less confident in?)

I would argue the secret isn't being kept. It just circulates in one silo and not all silos of our reality schism.
