Description
Melanotan 2 10mg — cyclic melanocortin agonist for research
Melanotan 2 10mg, also written melanotan-II or MT-2, is a synthetic cyclic heptapeptide melanocortin agonist supplied as lyophilized powder at 99%+ purity for in vitro receptor pharmacology research.
Ships from within the USA. Supplied for laboratory research use only, and not for human or veterinary use.
About MT-2 (Melanotan-II) 10mg
MT-2 is a cyclic lactam-bridged analogue of alpha-MSH. The ring constrains the peptide into a conformation that resists proteolysis and, unlike the MC1R-preferring linear analogue, it is a broad agonist across MC1R, MC3R, MC4R and MC5R. That lack of selectivity is precisely what makes it useful as a comparator: pairing it with a subtype-selective agonist in the same assay separates receptor-specific effects from pan-melanocortin ones.
Purity by reverse-phase HPLC, identity by mass spectrometry. Cyclic peptides can behave differently from linear ones on a chromatogram; the specification table below describes the material as supplied.
Research applications of MT-2 (Melanotan-II) 10mg
- Pan-melanocortin receptor pharmacology in transfected lines
- Paired comparison against subtype-selective agonists
- cAMP accumulation and functional receptor assays
- Tyrosinase and melanin readouts in melanocyte culture
- Conformational and stability studies on cyclic peptides
How this vial is supplied and handled
The vial arrives as a lyophilized cake or film in a sealed, stoppered vial. Keep it sealed and frozen at -20 °C until the day it is opened; brief periods at ambient temperature in transit are expected and do not compromise dry powder. Let the vial reach room temperature before breaking the seal so atmospheric moisture does not condense onto the cake.
Reconstitute by running the diluent slowly down the inside wall of the vial rather than onto the powder, and swirl rather than shake — peptides denature at an air-liquid interface. Hold the solution at 2–8 °C for short-term use, or aliquot and freeze for longer, and avoid repeated freeze-thaw cycles, the most common cause of a quiet loss of activity between one experiment and the next.
Ordering MELANOTAN-II 10mg in the United States
MELANOTAN-II 10mg ships to research laboratories throughout the USA, dispatched domestically from our US facility. Every parcel is tracked, and because the material stays inside the country there is no customs entry, no broker fee and no border hold between our shelf and your bench.
Shipping is calculated at checkout and orders over $200 USD ship free anywhere in the United States. Bulk pricing is available on larger quantities — email us before checkout and we will quote it.
Purity guarantee
If an independent laboratory tests this material and reports purity below the figure stated on its certificate, we refund the order and reimburse what the test cost you. Send the lot number printed on the vial along with the third-party report and we will settle it without argument.
The guarantee covers the analysis, not the outcome of your work. What MT-2 (Melanotan-II) 10mg does in your model is your experiment; what is in the vial is our responsibility.
Research use only
MT-2 (Melanotan-II) 10mg is supplied strictly for laboratory research carried out by qualified professionals. It is not a drug, a dietary supplement or a medical device.
It has not been evaluated or approved by the U.S. Food and Drug Administration for any use. It is not for human or veterinary consumption, for clinical investigation in human subjects, or for therapeutic, diagnostic or cosmetic application of any kind.
We do not provide dosing, administration or protocol advice, and we cannot answer questions about use in people or animals. By ordering, you confirm that you are acquiring this material for lawful research in a controlled laboratory setting and that you will not redistribute it for any other purpose.
Compound identity and specification
Identity data for Melanotan II, published so the material can be checked against an independent record rather than taken on trust. The formula, mass and registry number below are verified against PubChem and can be looked up directly.

Analytical note — Melanotan II. Cyclic, and one Da lighter than PT-141 because the C-terminus is an amide rather than a free acid. Any certificate that reports mass to the nearest whole number cannot distinguish the two, which is worth knowing when comparing suppliers.
Identity references The molecular formula, molecular mass and CAS registry number above are taken from the PubChem record linked in the table, not from a supplier datasheet, so every figure can be checked against an independent source in one click. Sequences are given as reported in the peptide literature, in the one-letter or three-letter convention as appropriate, with any non-standard residue named in full. Where a compound exists in more than one form — a free peptide and a metal complex, a fragment and its parent protein, a modified and an unmodified analog — the form supplied is the one identified here, and the mass on the certificate of analysis is what distinguishes it.
