If you scratch the surface of any of the peptide forums/discord Reta has been known and like Sema and Tirz is made (pirated, i guess would be the right word) in pharma labs from China, sold direct or through a US repackager since the first study white paper came out.

People are hungry for the new class of drugs and there’s a huge market being tapped by Chinese pharma to crank out these even while they are still in study/approval stage.
