What it is
Melanotan II is a cyclic heptapeptide analogue of α-MSH: Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2, 1024,2 g/mol, CAS 121062-08-6. A lactam bridge between aspartic acid and lysine closes the ring; within that ring lies the His-Phe-Arg-Trp core shared by all melanocortin peptides.
How it differs from Melanotan I
Melanotan I (afamelanotide) is linear, consists of thirteen amino acids, and primarily binds to MC1R. Melanotan II is shorter and cyclic, and is described in the literature as a non-selective agonist of the melanocortin receptors MC1R, MC3R, MC4R, and MC5R.
In the vial
Lyophilized powder, reconstitute with bacteriostatic water; unopened at −20 °C, reconstituted at 2–8 °C. The lab report on this page shows per variant which report belongs to it, what strength it has, and how to verify it yourself with the lab.

Stap 1
Purity by HPLC
Liquid chromatography separates the sample; purity is the proportion represented by the main peak.
Stap 2
Identity by FTIR
FTIR compares the sample’s infrared spectrum with a reference spectrum to confirm identity.
Stap 3
Content by quantitative testing
A separate measurement determines how much substance is in the vial, where included in the report.

Calculation rule: concentration (mg/ml) = mg in the vial ÷ ml bacteriostatic water. Example: 10 mg in 2 ml = 5 mg/ml, 10 mg in 3 ml ≈ 3,33 mg/ml. Let the water run down the glass wall and swirl until the solution is clear, do not shake; work aseptically. The vial content of this product has not yet been confirmed: the calculator remains in manual mode until it is known.

What is the difference between Melanotan II and Melanotan I?
Melanotan II is cyclic, has 7 amino acids, and targets MC1R, MC3R, MC4R, and MC5R. Melanotan I (afamelanotide) is linear, has 13 amino acids, and primarily binds to MC1R. They are two different substances, not strengths of a single product.
Is Melanotan II a registered medicinal product?
No, nowhere. This product is exclusively laboratory material and not intended for use in humans or animals.
Which lab report belongs to Melanotan II?
In the lab report block on this page. There you see which report belongs to the selected variant, what strength it is, and how to verify it with the lab yourself.
Why does the report mention 'acetate'?
Peptides are often supplied as an acetate salt. The molecular mass on this page (1024,2 g/mol) is that of the peptide itself, without counterion.
How do I store Melanotan II?
Unopened at −20 °C, dark and dry. After reconstitution at 2–8 °C, typically within 28–30 days.
How do I reconstitute Melanotan II?
With bacteriostatic water along the glass wall, then swirl until clear, do not shake. The concentration is mg in the vial divided by ml water; the peptide calculator calculates it.
How quickly is it shipped, and does it need to be refrigerated?
Ordered and paid on business days before 22:00, it is dispatched the same day: the Netherlands the next business day, other EU countries in 1–4 business days. The lyophilised powder travels dry and in neutral packaging; place the vial at −20 °C immediately upon receipt.
What is in the packaging?
One vial with lyophilized powder, neutrally packaged with sender. Bacteriostatic water, syringes, and alcohol wipes are not included as standard; these can be ordered separately under 'Complete your research'.
How do I place an order?
Place products in your shopping cart and complete the order at checkout. There you enter your details, choose a payment method, and confirm the three mandatory declarations. You will immediately receive a confirmation by email with the overview and, in case of payment by bank transfer, the payment details.
When will my order be shipped?
Ordered and paid before 22:00 on business days: shipped the same day. In the case of a bank transfer, the time your payment is received applies. After 22:00, on weekends, or on public holidays, your order will be dispatched on the next business day. If it is busy, this will be stated at the top of the site with the new shipping date.
