Basically it's a synthetic analog of α-MSH, sequence Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2, that hits MC1R and MC4R for melanogenesis and metabolic research — most buyers go with the 10mg vial for photoprotection studies or appetite regulation work.
Purity runs >99%, and we usually have stock of teh, but confirm lead time if you need more than 50 vials or so (check lead time as production batches vary).
Storage is strict at -20°C — it's not something you leave at room temperture on bench, and solubility is straightforward in water for reconstitution, which is what it does best for melanogenesis assays.
Also, we include a COA with each order, the 1024.19 g/mol molecular weight matters for accurate dosing in your protocols, and the 10mg/vial packging is pretty standdard for single-use or small-scale studies.
Not ideal for anything beyond research — this is not a clinical or cosmetic product, and we don't recommend it for in vivo work outside controlled lab settings.
It ensures minimal impurities—below 1%—so your melanogenesis or photoprotection studies aren't thrown off by side compounds. That's critical for consistent, repeatable results.
The peptide degrades quickly above freezing, losing potency in hours at room temp. -20°C locks in the structure, so you get the full 10mg active when you reconstitute.
Yes, it dissolves cleanly in water without harsh solvents—just sterile water or saline works fine. But always filter-sterilize before any in vivo work to avoid contamination.
We include a COA with HPLC purity data and mass spec confirmation of the full sequence, including the cyclic structure and norleucine modification. Just request it with your order.
Our standard is 10mg/vial for single-use research, but we can talk bulk discounts on larger peptide quantities or custom fill sizes for multi-dose studies. Minimum custom order usually starts at 100 vials.
