Melanotan II

Melanotan II 10mg is supplied as lyophilized powder under nitrogen. Typical reconstitution is in sterile or bacteriostatic water; the exact concentration depends on your protocol. Our free reconstitution calculator computes mL per dose and insulin-syringe units from any combination of vial size, water volume, and target dose.

Batch MT-2606 of Melanotan II 10mg is verified at 99.0% HPLC main-peak purity, with confirmation of molecular weight by LC-MS and endotoxin screening by LAL assay. One vial of every batch is also shipped to an independent US-based third-party lab for blinded re-verification. The full COA — including the chromatogram, mass spec trace, and third-party report — is bundled with your order as a downloadable PDF.

All orders ship cold-chain via DHL Express from our Guangzhou facility. Cold-pack is validated to hold under 8°C for 96 hours. Customs duties are prepaid by us — no surprise charges on delivery. Estimated transit time is 7-10 business days door to door. Tracking number is emailed when the shipment is scanned by DHL.

ACH bank transfer (2% off, recommended), USDC / BTC / ETH crypto (5% off), Zelle, CashApp, Venmo, or wire transfer for institutional orders. We do not accept credit cards because card processors prohibit research-peptide merchants in their terms of service. Full payment-method details are on the shipping & payment page.

Melanotan II has a plasma half-life of ~30 min in published pharmacokinetic studies. Most published research designs use single-dose or short-course protocols rather than chronic administration, partly because of the receptor desensitization patterns observed with prolonged melanocortin signaling.

Melanotan II is a non-selective melanocortin agonist — it activates MC1R, MC3R, MC4R, and MC5R. The non-selectivity means both central effects (via MC3R/MC4R) and peripheral pigmentation effects (via MC1R) are observed in research.
