For context, a lot of "For research use only" peptide websites sell retatrutide, which is like Ozempic but "better" (more mechanisms of action), and Eli Lilly is hoping to get it classified as a biological product which would provide them with something like a monopoly once it's approved. If these "For research use only" websites do not comply, I suspect the "For research use only" loophole will get closed given that Eli Lilly stands to make trillions of dollars from the drug.

Also, "For research use only" websites operate in the grey market and thus rather commonly accept bitcoin.
