I'm curious - why scary - they specialize in aquarium pharmaceuticals? Its a link on Humblefish's site (according to the poster above) - I called them they answered the phone after 1 ring, they have numerous products - and knew all about the indications, the regulations, and the shortages because people were using it for covid19 - and because its used in other countries for malaria - and there is a big push on for malaria treatment now?
EDIT - The lack of instructions is not an issue - thats in all of the protocols. I suppose I could call back and ask if this is 'pure' chloroquine phosphate - which would be my only concern - my understanding is that it was. (i.e. if you use 50 mg of the powder - are you really getting 50 mg - or is it 40 mg product and 10 mg filler, etc etc. I don't see a problem with the site (personally)
