@AL There sure is a lot of connections to the original manufacturer.... This is Page 1 and 2 of searching "Tiromel" on google images. These are all vendors, from all over the world.

The only people that legally have access to the original manufacturer are companies that stock medicine to sell to pharmacies. Pharmacies then proceed to resell them on the black market.
It is impossible for all these resellers, all over the globe to have access to this pharmaceutical, and then proceed to sell it for $20.
