I have an idea where. I don't care how much you hate me, disingenuity is not a good look.
If the packet says "not for human consumption" are you going to rush to take it, even if you have no indication you have the disease you are allegedly taking it for?
Chloroquine and HydroxyChloroquine are made and marketed (under prescription) for human use, primarily as anti malarial, for rheumatoid arthritis, systemic lupus erythematosus, and in the systemic therapy of amebic liver abscesses.
No mention of HOW MUCH they took, nor what they took it with, either.
If you are not a doctor nor a chemist, self-medicating can be a crapshoot. Self medicating with compounds not for human consumption is more into dangerous territory, and guessing dosages is like handloading rifle cartridges with an unknown powder. You might get away with it, but sooner or later, you're going to have a problem.
