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 — 10-Vial Pack

How is Melanotan I 10mg — 10-Vial Pack reconstituted?

+

Melanotan I 10mg — 10-Vial Pack 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 — 10-Vial Pack is verified in-house at 99.0% HPLC main-peak purity, with molecular weight confirmed by LC-MS and endotoxin screened by LAL assay. That in-house COA — chromatogram, mass spec trace, and purity call — is bundled with your order as a downloadable PDF. Independent third-party re-verification can be arranged for a specific batch on request; it isn't run by default.

How does QSC ship internationally?

+

All orders ship via DHL, UPS, or FedEx from our China facility, insulated for transit, to 58 countries. Customs duties are prepaid by us (DDP) — no surprise charges on delivery. Estimated transit time is about 10–15 days door to door. Tracking number is emailed when the shipment is scanned by the courier.

What payment methods are accepted?

+

One fully automated, self-serve method, 10% off: "Pay with crypto or card" at checkout takes a direct crypto payment from your own wallet (Bitcoin, Ethereum, USDT, USDC and more) or a normal card payment via our card-to-crypto processing partner — no crypto wallet needed for cards. Wire transfer, PayPal, and Revolut can be arranged by email before you order, at the regular price without the 10% discount. ACH is temporarily paused. 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.
