Calibrated active content, concentration or activity compared with the stated same-unit specification. Each row uses its own labeled scale; no conversion from chromatographic purity is made.
Melanotan II 10mg is a melanocortin receptor agonist supplied by Apex Laboratory as a high-purity research peptide intended strictly for in-vitro laboratory research and development applications.
Compound Overview
Melanotan II is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH). It is a non-selective agonist of melanocortin receptors MC1R through MC5R. Research interest centers on its activation of MC1R (melanogenesis), MC3R and MC4R (metabolic and appetite regulation), and related neuroendocrine signaling.
Research Background & Published Literature
Developed at the University of Arizona, Melanotan II has been studied in melanogenesis, photoprotection research, and melanocortin signaling. Published literature includes studies on melanocortin receptor subtype selectivity and downstream cAMP signaling cascades.

Storage, Handling & Stability Guidelines
Cyclic peptide structure provides enhanced stability compared to linear analogs. Store lyophilized at -20°C. Reconstituted solutions at 2–8°C, use within 30 days.
- Minimize time at ambient temperature during handling to preserve compound integrity.
- Avoid moisture exposure by resealing vials promptly after each withdrawal.
- Use appropriate personal protective equipment and follow your institution’s chemical safety protocols at all times.
- Label all aliquots with the compound name, concentration, date of reconstitution, and operator initials for complete traceability.
Quality Assurance & Analytical Verification
Apex Laboratory applies a dual-verification quality protocol to every batch before it enters inventory. Each lot undergoes High-Performance Liquid Chromatography (HPLC) to confirm chromatographic purity and Mass Spectrometry (MS) to verify molecular identity and molecular weight. This two-step analytical process ensures that the material you receive meets our ≥99% purity standard with confirmed molecular integrity. Certificates of Analysis documenting these results are available in the batch verification panel on this page and in the COA library for your internal quality records.
Frequently Asked Questions
Which melanocortin receptors does Melanotan II target?
Melanotan II is a non-selective agonist that activates MC1R through MC5R. Primary research interest focuses on MC1R (melanogenesis), MC3R, and MC4R (metabolic and neuroendocrine signaling).
How is Melanotan II structurally different from Melanotan I?
Melanotan II is a cyclic heptapeptide (7 amino acids, MW 1024.18 g/mol), while Melanotan I (afamelanotide) is a linear tridecapeptide (13 amino acids). The cyclic structure of MT-II provides broader melanocortin receptor activity.
