It's still expensive, but far cheaper than brand name with similar efficacy. Competition from these programs will likely drive costs much lower over the next few years.
Semaglutide is still under patent in the US till at least Dec 2031 (say Wpedia).
Blockbuster drugs still under patent usually don't have alternative avenues of supply that are significantly cheaper than the main avenue. I wonder what law or regulation allows this alternative avenue to persist.
