Why is Tessamorelin so expensive now

[swimmer]

After a 6 week break it's time to start pinning my favorite non-GLP peptide. I looked through my records and the last place I purchased it was SRY and SSA. It was only $110 per 10 mg kit and I think it was from the US warehouse. Now the cheapest I can find it is $158 from China. Other peptides I use have come down in price since the peptocolypse but not Tessa. I only have a 1/2 kit left and it goes fast.
