Ah, interesting. I keep hearing ads for a clinic that prescribes semaglutide at half the cost of Wegovy. I wondered how they can do that, if they are selling semaglutide and not some "supplement" they claim does the same thing. But I think this answers my question. Since the drugs have been around a long time, they must have lost their patent protection. So now, generics can be sold.
Semeglutide at half the cost of Wegovy is probably a compounded version. It would still be as effective but without the patented pen delivery much cheaper
