Won't be anywhere near that. I don't have prices handy, but Lilly sells tirzepatide (a bit better than sema, and usually a bit more expensive) at 500/mo (maybe a bit less now on the trump rx site, I don't recall). Depending on dose, that'll be about 10 bucks a mg give or take. At 50c/mg for sema you were paying a bit of a premium. These days even tirz is only about 30-35c/mg.
I used to buy from Peptide Sciences so I was certainly paying a premium for reputation at $20/mg. I think Semaglutide is now at a bit of a premium due to it falling out of favour and most people switching to Triz and Reta. I only take a low dose and am happy to stick with what's working.
There must be an irony that it was Trumps crackdown on peptides, I presume to prop up his prescription company, that forced me to switch to Chinese supply. By doing it all at once it created a critical mass for that market.
