Vladimir Zelenko is the famous doctor who developed or popularized successful use of HCQ+Zn for COVID. His treatment and preventive protocols were banned from twitter, but they are on his website here: vladimirzelenkomd.com
You can also get dirt-cheap HCQ and Ivermectin on Indiamart.com, which is like Ebay or Alibaba. The sellers are in India, so allow 4 weeks to receive a shipment. You have to pick a seller, and each seller has their own homepage on the site, usually with a custom domain name. If you log in to Indiamart and go to a seller’s page, they get notified, and they will contact you. You may get a ton of email offers from clicking around the website.
One Indiamart seller quoted the following prices.
100 tablets x Ivermectin-12mg $15
150 tablets x Hydroxychloroquine 200mg $20
Shipping for up to 1000 pills is $ 40 (Slow shipping)
You can negotiate, and all sellers will probably match these prices.
