There is no way for a compounder to acquire “legit” semaglutide or Tirzepatide as novo and Lilly are the sole manufacturers of it using the FDA approved process.

Every other source is acquiring the APIs from China and effectively buying from the same sources that the random sites selling a vial of lypholized “research chemical” powder are getting it from.

The huge compounding companies might skip the lypholization step and mix it directly due to cost savings at scale, but it’s effectively the same sources you could buy direct from China from if you spent a bit of time researching.
