Actually, we had to sort through a few suppilers that quoted HPLC purity in the high 90s but couldn't back it up with batch-specific reports — this one lands at >99% by HPLC and that spec holds across the vials we've tested, (check lead time on the COA for your records, usually 2-4 weeks).
The molecular weight is 1024.2 g/mol, the CAS is 121062-08-6, and it come as a sealed under inert gas — we store ours at -20°C in the dark since it degrades pretty quickly if left out, and most labs we work with reconstitute in sterile bacteriostatic water at about 1mg/mL or so.
What it does is activate MC1R to drive melanogenesis, but you'll want to keep in mind it's not a great fit for any kind of in vivo work with human subjects — research use only, and the melting point is >200°C (dec.) so don't try to heat it up for solubility.
We usually have stock in 10mg, 25mg, and 50mg sealed vials, but if you need a different format or a bulk lot with tighter tolerance on peptide content, shoot me volume and I can check what the lab can do — they've done custom fills for guys doing long-term pigmentation studies before.
One thing you wouldn't think to ask is the peptide sequence is Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2, which means teh cyclization is pretty stable, but solubility can be hit-or-miss if you use plain water instead of sterile bacteriostatic water — we've seen clumping at the 5mg/mL range.
Anyway, we ordered 50 vials of the 10mg because of that it's what most buyers go with for initial dose-response work, and the lead time form order is typically 10 business days or so.
It means our Melanotan II is at least 99% pure as tested by HPLC, so you're getting a consistent, high-quality peptide with minimal impurities. This helps ensure reliable data in your melanogenesis or pigmentation studies.
Yes, we include a COA for every batch, showing the HPLC purity, mass spec confirmation, and other specs like appearance and solubility. Just request it with your order.
We don't have a strict MOQ—you can order as little as one vial for small-scale research. Larger quantities are available if you need them.
Orders typically ship within 1-3 business days. We pack the vials with ice packs and insulated containers to keep them cold during transit, so just store them at -20°C as soon as they arrive.
Custom packaging is possible—just let us know your preferred vial size or gas overlay, and we can arrange it for bulk orders. Minimum custom quantity may apply.
