You might have more luck getting Bimectin (the horse paste, which is pure ivermectin & perfectly ok for humans if you make sure you adjust the dose) - that is what I did, here in Australia where IVM is also not available & they are very strict about importing drugs. Also, I got bulk Ascorbic Acid and Quercetin from ebay - these are not considered pharmaceuticals (not yet!) so there is not the same concern from Customs.
