Research topic
Melanotan I (afamelanotide) and Melanotan II — two analogues of α-MSH for melanocortin and pigmentation research, in lyophilized vials, ten per kit.
Both peptides are modelled on alpha-melanocyte-stimulating hormone (α-MSH), the peptide hormone of the melanocortin system. Melanotan I is the linear analogue of thirteen residues known by its international name, afamelanotide; Melanotan II is a shorter, cyclic analogue. Sequence, formula, mass and CAS differ, so each has its own page and fact table.
Afamelanotide is the active substance of an approved implant: the vials we supply hold the same molecule, but they are not a medicine. Melanotan II has no approval. Both are stocked with catalogue codes and a COA for every lot. KPV, a tripeptide from the end of α-MSH, is listed under skin and ageing.
Melanotan I (afamelanotide), a linear analogue of α-MSH, and Melanotan II, a cyclic one — the two peptides of the pigmentation research topic.
Grouped as α-MSH analogues by the database record or the study cited on each page.
The studies recorded in our product data for the products of this topic (checked 2026-10-09): who led the study or which trial it was, the year, the journal and what was examined. They show what has been researched with each molecule, not results for the vials we supply.
| Product | First author / trial | Year | Journal | What was studied | Record |
|---|---|---|---|---|---|
| Melanotan II | Dorr RT | 1996 | — | Pilot phase-I evaluation of Melanotan II in a small group of male volunteers | PubMed 8637402 |
Every lot of a stocked product has its own batch COA. Ask for the COA of the batch you are quoted before you order: the lot number on it is the lot we ship.
What the COA reportsMelanotan I, Melanotan II — each with catalogue codes, kits of 10 vials from 1 kit, and a batch COA for every lot.
In size and shape: Melanotan I is a linear chain of thirteen residues, Melanotan II a ring of seven. Each has its own formula, molecular weight and CAS number in its fact table.
No. The approved product is a finished implant that contains afamelanotide. Our vials hold the same molecule as lyophilized research material, which is not a medicine.
Yes — from one kit of each, on a single written quotation that states the unit price per kit, shipping and lead time.
