Melanocortin Agonist
Melanotan II
Melanocortin Analog
Melanotan II is a lab-made copy of a natural hormone that controls skin pigment. It is researched for how the skin produces melanin, the pigment behind tanning. In studies it activates the same receptors the body uses to deepen skin color, and it is also examined in appetite-signaling research.

Overview
Melanotan II is a synthetic melanocortin agonist supplied strictly as a reference material for laboratory research. In the published literature, this class of peptide is studied for how it engages the melanocortin receptor family, the same receptor system associated with melanin production in research models. VANTA provides Melanotan II peptide as a lyophilized powder so research teams can characterize melanogenesis and pigmentation signaling in controlled in-vitro and preclinical models, with identity and purity documented per lot.
Researchers reference Melanotan II across three primary areas in the literature: melanogenesis, pigmentation, and appetite signaling. These are the research contexts in which the molecule appears in the scientific record, described only as observations within laboratory and animal models rather than as outcomes in people. Because melanocortin signaling is studied through receptor-sensitive readouts, the analytical integrity of the test article matters, which is why each batch of research grade Melanotan II ships with verification data tied to its specific lot.
When you buy Melanotan II through VANTA, every lot is third-party HPLC tested and confirmed by mass spectrometry, with a Certificate of Analysis documenting the result. This per-batch approach lets a laboratory attribute experimental findings to the intended melanocortin agonist rather than to impurities or truncation products. All Melanotan II is sold for laboratory research use only and is not a drug, supplement, or article intended for any form of human or veterinary use.
Research Areas
Handling & Reconstitution
Melanotan II is supplied as a lyophilized powder for laboratory reconstitution. Researchers generally store the sealed vial at -20C and reconstitute with an appropriate solvent immediately before experimental use, following their own institutional protocols. Reconstituted material is typically kept refrigerated and protected from light. These are general reference points for laboratory handling, not instructions for any in-vivo or human application.
Frequently asked questions
What is Melanotan II?
Melanotan II is a synthetic peptide classified as a melanocortin agonist. In the research literature it is studied for how it engages the melanocortin receptor system associated with melanin production in research models. VANTA supplies it strictly as a reference-grade material for in-vitro and laboratory research, not for human or veterinary use.
What form does Melanotan II ship in and what purity?
VANTA supplies Melanotan II peptide as a lyophilized powder. Each lot is third-party HPLC tested to quantify chromatographic purity, with our specification targeting high purity (99%), and identity is confirmed by mass spectrometry so researchers can attribute results to the intended melanocortin agonist.
How should researchers store and reconstitute Melanotan II?
The lyophilized vial is generally stored at -20C and reconstituted with an appropriate solvent immediately before experimental use, following institutional protocols. Reconstituted material is typically refrigerated and protected from light. These notes are for laboratory handling only, not guidance for any administration.
Is each batch of Melanotan II third-party tested with a COA?
Yes. Every lot of research grade Melanotan II is assessed by reversed-phase HPLC for purity and confirmed by mass spectrometry for identity. Each batch ships with a per-batch Certificate of Analysis documenting these results, so a laboratory can tie each experiment to a specific, traceable lot.
How does Melanotan II differ from Melanotan I in research?
Both appear in the melanocortin literature as compounds studied in pigmentation and melanogenesis research models, and researchers reference Melanotan II as a distinct sequence with its own analytical profile. VANTA describes these only as research-context distinctions and supplies each compound for laboratory use only, making no claims about effect.
Is Melanotan II intended for human use?
No. Melanotan II is supplied strictly for laboratory and in-vitro research use by qualified professionals. It is not a drug, supplement, food, or cosmetic, and it is not intended for human consumption, administration, or any form of human or veterinary use.
