Synonyms: Melanotan II, MT-II, [Nle4, D-Phe7]-α-MSH, NDP-α-MSH, Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2, C50H69N15O9, 121062-08-6

Buyers sourcing Melanotan 2 are typically compounding pharmacies, wellness clinics and research houses that need a reliable, high-purity peptide for formulations where controlled pigmentation and tanning response matter. The ingredient moves in small, high-value lots, and the purchasing decision usually comes down to assay consistency, correct handling and documentation that stands up to audit.

Melanotan 2 is a synthetic cyclic heptapeptide analogue of alpha-melanocyte stimulating hormone. It is manufactured by solid-phase peptide synthesis, purified by preparative HPLC, and supplied as a lyophilized powder with a guaranteed purity of ≥98.0% by HPLC. Each batch is released against a certificate of analysis that reports the actual assay and identity data, so formulators can verify what they are receiving before it enters production.

Because the peptide is moisture- and heat-sensitive, it ships in sealed vials under desiccant and should be stored at -20°C for long-term stability. Working solutions are typically prepared in bacteriostatic water or sterile saline and kept refrigerated. The notes below cover the supply forms we keep in stock, how the material behaves in typical compounding and research settings, and the ordering terms.

Grade & Supply Forms

We supply Melanotan 2 as a research-grade and pharmaceutical-grade peptide, both produced under the same synthesis and purification route. The difference is in the documentation package and the release testing applied to the batch, which we can tailor to your market. Standard stock is the lyophilized powder in sealed vials; it dissolves readily in water and sterile isotonic solutions, which suits injectable compounding and laboratory reconstitution alike.

Purity is the main specification buyers screen on. Our routine stock runs at ≥98.0% by HPLC, with the chromatogram and mass spectrometry confirmation included in the COA. If you need a tighter window or a specific counter-ion, tell us before the order is placed and we will confirm what can be committed on the batch.

Applications & Formulation Use

Most volume goes into injectable compounding for tanning and pigmentation protocols, where the peptide is reconstituted and filled in small multi-dose vials. Compounding pharmacies and clinics use it as the active in ready-to-use pens, prefilled syringes and sterile vials, and they depend on consistent assay from lot to lot because the final dose is measured in micrograms.

Research groups buy the same powder for in-vitro work and animal studies, usually in 1 g to 10 g quantities. In those settings the peptide is dissolved in buffer or saline and used fresh, since solutions lose potency on repeated freeze-thaw cycles. It is not a cosmetic raw material and not intended for topical or oral formulations; the commercial demand is concentrated in parenteral and laboratory use.
