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 cyclic melanocortin analogue studied in receptor research and early clinical experiments. Read each receptor-specific assay and tested population separately; the class label does not establish activity at every melanocortin receptor or a biological property of this supplied configuration.
Research Background & Published Literature
Hadley and Dorr reviewed the historical development of melanocortin analogues, distinguishing linear melanotan I, cyclic melanotan II and later PT-141 work. The review is historical context; its development-stage statements are not a current regulatory status or evidence about this supplied lot.
Dorr and colleagues reported a small pilot phase-I study of melanotan-II in three male volunteers, including pigmentation observations and adverse effects. The sample and early design limit inference. The clinical study does not establish the safety, suitability or therapeutic use of the reagent sold here.

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
Review the tests recorded for the applicable configuration and lot. The published Apex Laboratory record identifies the issuer, methods, results, units and acceptance criteria. A public configuration record does not by itself identify the lot currently shipping or establish independent accreditation.
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.
Is this product approved for human use?
No. All compounds sold by Apex Laboratory are classified as chemical research reagents intended strictly for in-vitro laboratory research. They are not approved for human consumption, veterinary use, or any therapeutic application. Purchasers who imply intended bodily use will have their orders cancelled and accounts permanently suspended.
What documentation is available for this compound?
Open the applicable published configuration and lot record in the COA library. Read its issuer, methods, results, units and reporting limits, and match the complete lot on your material. If a particular lot or additional documentation is required, contact support before ordering; publication alone does not identify the lot that will ship.
Is bulk ordering available?
Yes. For bulk quantities, custom packaging requirements, or recurring supply agreements, contact our team with the compound name, desired quantity, preferred research-material format, and your target delivery timeline. Volume pricing is available for qualifying orders.
