Description
Melanotan II — Research Peptide
Melanotan II is a synthetic cyclic heptapeptide referenced in scientific literature as a non-selective melanocortin receptor agonist, classified within the melanocortin pathway research peptide family.
Purity: ≥99% (HPLC-MS verified)
Format: 10mg lyophilized vial, sealed amber glass
Designation: Research use only — not intended for human or veterinary use
Compound Overview
Melanotan II is a 7-amino-acid synthetic cyclic peptide structurally related to α-melanocyte-stimulating hormone (α-MSH). Within published research literature, it is studied as a non-selective melanocortin receptor agonist with activity across MC1R, MC3R, MC4R, and MC5R receptor subtypes.
Melanotan II is frequently studied in adjacency to PT-141 (a closely related melanocortin-class cyclic heptapeptide) and KPV (the α-MSH C-terminal tripeptide fragment), as part of the broader melanocortin pathway research literature.
Research Context
Melanotan II has been investigated in published research literature and is commonly referenced in laboratory work involving:
- Melanocortin receptor pharmacology research
- Non-selective MC1R/MC3R/MC4R/MC5R receptor research
- α-MSH-pathway comparative research
- Cyclic peptide structure–activity research
- Comparative melanocortin peptide pharmacokinetics
- Neuropeptide signaling research models

Frequently Asked Questions
How does Melanotan II differ from PT-141?
Both are synthetic cyclic heptapeptides referenced as melanocortin receptor agonists. They occupy related but distinct positions within melanocortin-pathway research literature.
What purity standard does DISSOLV LABS supply?
DISSOLV LABS supplies Melanotan II at ≥99% purity, verified by reversed-phase HPLC and confirmed by mass spectrometry (HPLC-MS). Each lot is accompanied by a Certificate of Analysis.
What analytical testing is performed on each lot?
Each Melanotan II lot is subjected to RP-HPLC purity analysis, HPLC-MS identity confirmation, residual solvent and moisture screening, and batch-consistency documentation. Third-party analytical verification is available upon institutional request.
How should Melanotan II be stored?
Recommended storage is −20 °C, protected from light and moisture, in the original sealed vial. Refer to the lot-specific Certificate of Analysis for stability data.
How is Melanotan II reconstituted for laboratory work?
Melanotan II is typically reconstituted with sterile or bacteriostatic solvent in accordance with the receiving laboratory's internal protocols. Reconstitution methodology is the responsibility of the qualified research professional.
