MELANOTAN II
Melanotan II is a cyclic lactam analogue of alpha-melanocyte-stimulating hormone (α-MSH) and a non-selective melanocortin-receptor agonist. It is studied in pigmentation and melanocortin-signalling research, and is the parent structure from which the MC3R/MC4R-selective analogue bremelanotide (PT-141) was derived.

Research summaries
For educational purposes only.
Melanocortin agonism and melanogenesis
Preclinical and early clinical pharmacology characterizes Melanotan II as a broad agonist across MC1R, MC3R, MC4R and MC5R. MC1R activation on melanocytes increases eumelanin synthesis, which underlies the pigmentation endpoints reported in dermatological research on superpotent α-MSH analogues.
In plain English
Melanotan II activates several melanocortin receptors at once, unlike PT-141 which is more selective. Its pigmentation effects come from MC1R activity on melanocytes.
Off-target melanocortin effects and safety signals
Case-series literature on unregulated Melanotan II use documents adverse events including nausea, blood-pressure changes, and reports of eruptive or changing melanocytic naevi, prompting dermatology-society warnings. These reports concern unsupervised human use, not controlled research settings.
In plain English
The published safety literature on Melanotan II is largely case reports from unregulated use, and it is a standard consideration in study design with this peptide.
Melanotan II — Frequently asked questions
What is Melanotan II?
Melanotan II is a cyclic lactam analogue of alpha-melanocyte-stimulating hormone (α-MSH) and a non-selective melanocortin-receptor agonist. It is sold strictly for laboratory research use — not for human or veterinary use.
What purity is this Melanotan II?
The catalog specification lists 99.36% HPLC purity. Our testing policy also requires independent endotoxin, heavy-metals and sterility screening. An independent report from Janoshik Analytical is linked in the Certificates tab; a production certificate must match the batch ID printed on the vial.
What sizes does Melanotan II come in?
Melanotan II (10mg vials) is offered in 20mg, 50mg, 100mg boxes (2 × 10mg vials, 5 × 10mg vials, 10 × 10mg vials), priced $62.00 to $235.00 — the per-mg cost falls as box size increases.
How should Melanotan II be stored?
Keep sealed lyophilized vials refrigerated at 2–8°C away from light (stable 24+ months). After reconstitution with bacteriostatic water, refrigerate and use within the study-validated window, typically 30 days; never freeze reconstituted solution.
Storage details
Lyophilized (as shipped): store refrigerated at 2–8°C away from light. Sealed vials remain stable for 24+ months; short excursions at room temperature during transit do not affect stability.
After reconstitution: store at 2–8°C and use within the study-validated window (typically 30 days with bacteriostatic water). Do not freeze reconstituted solution.
Handling: direct diluent down the vial wall and swirl gently — never shake. Peptide bonds are mechanically fragile in solution.
Light: keep vials in the box or amber sleeve; repeated light exposure accelerates degradation of Melanotan II.
