I'm far from convinced that some random "compounding pharmacy" produces effectively the same thing as Ozempic.
We already know that the compounding pharmacies violate patent law. Why should I believe they follow any other regulation?
The hard part is discovering them and proving they're safe and effective.

And this type of drug lends itself to some of the least expensive trials you can hope for. The dosage level, expected dosing period, and measurement of outcomes are all uniquely well suited to inexpensive study. The trials were also exceedingly fast and quickly broke off into testing for all kinds of conditions such as Parkinsons but for the core case of weight loss it was as easy as it gets.
