About this peptide

Melanotan I (Afamelanotide, [Nle4, D-Phe7]-α-MSH) is a synthetic linear analog of alpha-melanocyte stimulating hormone with two amino acid substitutions that greatly increase metabolic stability and MC1R selectivity relative to native alpha-MSH. Compared with the cyclic Melanotan II, Melanotan I is largely selective for MC1R and shows minimal MC3R/MC4R activity — the basis for its use as a "cleaner" pigmentation-pathway probe with fewer confounding appetite or arousal effects in animal studies. Supplied as lyophilized acetate salt. Reconstitute at 2–5 mg/mL in sterile or bacteriostatic water. Light-sensitive — store away from direct light.

Questions about Melanotan I 10mg

How is Melanotan I 10mg reconstituted?

+

Melanotan I 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.

What is the HPLC purity of this batch?

+

Batch M1-2607 of Melanotan I 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.

How does Vesta ship to the United States?

+

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.

What payment methods are accepted?

+

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.

What is the plasma half-life of Melanotan I?

+

Melanotan I has a plasma half-life of ~1 hr 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.

How selective is Melanotan I across melanocortin receptors?

+

Selectivity profiles vary across melanocortin family compounds and determine which physiological pathways are primarily activated. See the molecule-specific characterization in published literature for receptor binding data.
