If your from Europe, you can order Ivermectine from this shop:
and search for eqimectin 800.
During the payment process, select pick up by postal service and let the prescription be done by the shop.
It works, I have 6 tubes now, maybe you could also order international, but there's customs coming into play.
Edit: fixed the link.
If you search for ivermectin, you get a whole bunch of different pastes:

Thanks, but why is this preferable over the other products? Asking as a layman ..
To be fair, I don't know. That's what I ordered, the ammount of Ivermectin was high enough, easy to apply, so that's just it. Relevant for humans is imo the purest Ivermectin you can get. It's the same drug, humans, animals, it doesn't matter.
And it comes in a handy applicator that fits up your arse. :)
