Research Peptide | Lyophilized Powder | Batch Tested
For laboratory research use only. Not for human or animal consumption. Insulated shipping · Styrofoam box available.
Product Overview
Melanotan II is a synthetic cyclic melanocortin-receptor agonist with broader, less selective activity than Melanotan I, engaging several melanocortin receptors including MC1R and MC4R. This wider activity makes it a tool for studying both pigmentation and central melanocortin pathways.

Product & documentation questions
How do I read the size and pack quantity?
The per-vial size and number of vials per pack are listed separately in the table. The displayed price is for one pack. A blend’s stated size can describe combined ingredients; check its product label and report for individual components.
How do I find the matching COA?
Match the product, SKU and batch number with the published report. Open the batch page to read the actual results, original report and laboratory verification link. Ask support to confirm the allocated batch if it is not on your order.
Does a purity result mean every test passed?
No. Identity, purity, fill and endotoxin are separate measurements. Read each reported result and unit. An absent result is not a pass, and a less-than result is not zero.
Research Information
Melanotan II is used to study non-selective melanocortin signaling and its effects on melanogenesis as well as central pathways governing appetite and sexual behavior (via MC4R) in laboratory models, allowing comparison against the MC1R-selective Melanotan I. Supplied strictly for in-vitro and laboratory research use only — not for human or animal consumption.
