Melanotan Peptides
Melanotan I 10mg — Research Peptide Canada
Melanotan I (afamelanotide) is a linear alpha-MSH analogue, [Nle4, D-Phe7]-alpha-MSH, with high selectivity for the MC1 receptor. That selectivity is what separates it from Melanotan II, which is cyclic and active across MC1, MC3, MC4 and MC5.

About Melanotan I 10mg
Melanotan I is studied primarily in melanocortin-1 receptor signalling and eumelanin synthesis models. The two substitutions that define it, norleucine at position 4 and D-phenylalanine at position 7, confer resistance to enzymatic degradation while preserving MC1R affinity. Because it lacks meaningful MC3 and MC4 activity, it is the more selective of the two Melanotan research materials and is often used as the control arm when investigators need to separate MC1R-mediated pigmentation effects from the broader melanocortin activity of Melanotan II.
Storing and handling Melanotan I 10mg
Store lyophilized peptide at -20°C in a dry, dark environment. Reconstitute in bacteriostatic water. Once reconstituted, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles. Lyophilized powder is stable at room temperature for shipping and short-term storage.

Melanotan I 10mg questions
Are research peptides like Melanotan I 10mg legal in Canada?
Melanotan I 10mg is supplied here strictly as a reference material for in vitro laboratory research. For laboratory research use only. Not for human or veterinary use. Canadian law turns on what a substance is represented and supplied for, which is why that restriction is on the label, the invoice and every page of this site. The full framework, and what a research-use designation does and does not change, is set out on our legality page.
Is Melanotan I 10mg shipped from within Canada?
Yes. Every Melanotan I 10mg order leaves British Columbia, Canada and travels entirely within the country. Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Transit after dispatch is 2–5 business days Canada-wide, with a tracking number on every parcel, and orders over CA$200 ship free.
Does Melanotan I 10mg come with a certificate of analysis?
Yes — the certificate for the lot in your box, not a representative certificate for a different batch. Every Melanotan I 10mg lot is released against a >99% HPLC specification, and the document carries the lot number, the issuing laboratory and the analytical method. Certificates are not published on this site; if you need another copy, ask us for it by lot number.
How is Melanotan I 10mg supplied and stored?
As a lyophilised powder in a sealed vial, which is the form that survives shipping without a cold chain. Unopened vials are stored away from light and moisture; the storage and handling page covers the laboratory conditions in full. We publish no dosing, reconstitution volumes or administration guidance of any kind.
What fill is Melanotan I 10mg supplied in?
Melanotan I 10mg is supplied in a single 10mg fill, released against a >99% specification.
