Thanks for reaching out, and yeah, we’ve got the compounds you mentioned covered — Kisspeptin-10 comes in at a molecular weight of 1302.4, CAS 374675-21-5, and we typically see purity above 98% on COA, though it varies slightly batch to batch.


Basically, what it does is it’s classified as a bulk drug intermediate, so it’s not something you’d use directly in vivo without further work — most buyers go with the 10mg vial for initial assays, and we usually have stock, but confirm lead time if you’re in a hurry.

For Tirzepatide, CAS 2023788-19-2, teh molar mass runs about 4813.45, and it’s a white powder; you’ll want to store it dry and dark at 0-4°C short-term or -20°C long-term, or it degrades faster than you’d expect — shelf life is >2 years if handled right.

P21 (Cip1) is actually a small molecule here, not a peptide, with a melting point around 69-73°C and solubility in methanol at 0.1 g/mL, so it’s better suited for solvent-based work than aqueous systems — just a heads-up if you’re planning formulations.


Pricing depends on quantiy, but we’re competitive on the semaglutide injection side too, and our company can do custom packaing in 50mg or 100mg vials; lead time is roughly 15-20 days or so, depending on whether we’ve got a current production run.
We can do as little as 1 gram for Kisspeptin-10, but if you're ordering regularly, we can negotiate better pricing for larger volumes.
Yes, every batch of Tirzepatide comes with a CoA that includes purity data—typically >98%—and other specs like appearance and storage info.
For stock items like P21, lead time is usually 3-5 business days. Custom orders or larger quantities might take 7-10 days depending on the volume.
Sure, we can customize labels and packaging for Kisspeptin-10 to meet your research specs—just let us know the details before production.
Store Tirzepatide in a dry, dark place at 0-4°C for short-term use, or at -20°C for longer storage. Properly stored, it stays stable for over 2 years.
