99% Pure Melanotan 2 Powder MT2 Peptide for Research - High Purity Melanotan II

The 99% purity on this batch is confirmed by HPLC, and we actually ran it through a second round of testing to be sure. We've seen some supliers claim that number and ship stuff at 96% or so, which makes a difference when you're titrating doses in a study that lasts months.

You'll get a white powder—off-white if it's been sitting a bit—in sealed vials with desiccant, and we usually have stock for the 1 gram MOQ, but confirm lead time if you need more than 50 units. Just keep it at 2-8°C and dry, it's stable for about 24 months that way, though some researchers push it to 30.

Most buyers go with the 1 gram sample first to run a quick solubility test in water, and what it does is dissolve cleanly with no particulates. The 1024.2 g/mol molecular weight is standerd, but we pack it with a tight tolerance on vial fills (usually within 5mg), so your reconstitution calculations don't wander.

One thing to watch—this isn't great for any in vivo work with long-term storage at room temp, the peptide degrades noticeably. We've had a few clients try to stretch it, and the loss in activity is pretty clear by month six. Anyway, for research use only, it's a solid tool for melanogenesis or feeding behavior studies, and we include sequence (the Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2) on the COA form GMP-certified production.
