When I initially looked at ivermectin vendors, I came across
Seven Cells that were selling $10 per 16 mg capsule, which is really pricy. However, I discovered from another thread here that people were getting ivermectin from India, and they ship to lots of places at cheaper rates. That's when I discovered Lifebelt Corporation and had a chat with them via email to
buy some of their ivermectin (iversun brand) tablets.
I'm from the USA and the shipping cost for me was around $47 from India, but the cost per 10 tablets was so low, so I ordered a lot to make it worth it (and its still cheaper than Seven Cells). It takes some weeks to ship, but I ended up getting it in the end and didn't run into any problems.
I'm hoping those clots aren't actually parasites, but ivermectin can also help in other areas. Those with weakened immune systems are also susceptible to all manner of dirty critters like viruses, etc., so these won't hurt to have I'd imagine
