Melanotan 2 at a glance

Melanotan 2 is a lactam-bridged cyclic peptide modeled on alpha-MSH, the pituitary hormone that signals pigment cells. Its molecular formula is C50H69N15O9 and its molecular weight 1024.18 g/mol. Researchers at the University of Arizona created it while looking for a way to induce skin pigmentation without sun exposure. Ring closure and the inclusion of a D-phenylalanine residue make it far more resistant to enzymatic breakdown than the natural hormone it imitates.

Price and availability

Sold by Sulan Bio and sent from Guangzhou, China, this listing is a kit of 10 vials at 10mg each (100 mg in total). $100.00 buys the whole kit, which is $1.00/mg. 13 brands sell Melanotan 2 on GLP1 Forum Escrow, with a typical price of $0.468–$3.85 per mg (median $1.00); this listing is inside that range. Funds stay in escrow and are released to Sulan Bio only when you mark the order as received.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

What it is studied for

MT-2 acts as an agonist across MC1R, MC3R, MC4R and MC5R, with little selectivity among them. On melanocytes, MC1R stimulation raises cAMP and shifts production toward eumelanin, the darker pigment. In the central nervous system, MC4R and MC3R engagement is linked in animal studies to reduced food intake and to erectile responses, the latter observation leading directly to bremelanotide. MC5R, found in exocrine glands, is less well studied. Because one molecule touches so many receptor subtypes, attributing any single observed effect to one pathway is difficult.

Research and regulatory status

Small early human studies from Arizona explored tanning and erectile responses, but MT-2 was never taken through full clinical development and has no approval anywhere. Regulators in several countries, including the UK and Australia, have issued warnings about unlicensed products sold online. Its research value today lies in melanocortin pharmacology, where it serves as a broad reference agonist. Case reports have described changes in moles among people using unregulated material, adding to calls for caution.

Checking the lab data

Mass spectrometry should match 1024.18 g/mol. Since PT-141 differs from MT-2 by roughly one mass unit at the C-terminus, high-resolution data or a reference retention time helps confirm the right compound. HPLC purity should be backed by an actual chromatogram for the specific lot. The freeze-dried cake normally appears white to off-white. Independent testing with a visible batch number and date is preferable to in-house certificates.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

Concentration arithmetic: one 10 mg vial dissolved in 2 mL gives 5 mg/mL, or 10 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.

Buyer questions

Why is Melanotan 2 cyclic?

Linear alpha-MSH is broken down rapidly by peptidases. Joining two side chains into a lactam ring constrains the molecule's shape, which protects it from those enzymes and holds it in a conformation that binds melanocortin receptors strongly. That structural choice is the main reason MT-2 is so much more persistent than the natural hormone.

Have regulators commented on Melanotan 2?

Yes. Medicines agencies in several countries have warned that Melanotan products sold online are unlicensed and that their quality and composition are unknown. Those warnings concern unregulated supply rather than laboratory research, but they are a good reason to look closely at independent analytical reports for any listing.

How much Melanotan 2 is in this listing?

10 vials of 10mg each — 100 mg in all. Where a lab report exists, the testing panel above shows what the brand's tested sample actually measured.
