Melanotan Peptides
Melanotan I 10mg
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.
Storage and reconstitution
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.
Shipping within Canada
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. Parcels leave British Columbia, Canada and travel entirely within the country, so nothing on this order crosses a border, clears customs or is held by CBSA. Orders over CA$200 ship free; see the shipping page for transit times by province.
