Melanocortin Agonists

Peptide Warehouse Australia stocks Melanotan I 10mg and Melanotan II 10mg, both supplied as lyophilised powder at 99%+ HPLC purity. They are for in-vitro laboratory research only and are dispatched from our Australian warehouse with full Certificate of Analysis documentation.

Melanotan I (afamelanotide) is a linear alpha-MSH analogue that selectively activates MC1R receptors. Melanotan II is a cyclic analogue of alpha-MSH with broader receptor affinity, targeting MC1R, MC3R, MC4R, and MC5R. The additional receptor targets of Melanotan II produce distinct effects in research models. Both are synthetic melanocortin peptides for in-vitro research use only.

Melanotan II is available for purchase in Australia for legitimate in-vitro laboratory and research purposes. Purchasers must be 18+ and confirm research-only use at checkout. It is not approved by the TGA for therapeutic or cosmetic use. For research use only. See our Legal page for full information.

Store lyophilised Melanotan II at −20°C long term. For reconstitution, inject 1–2mL of bacteriostatic water slowly along the inside wall of the vial and gently swirl until dissolved. Store reconstituted solution at 2–8°C for up to 4 weeks, protected from light. Use our Peptide Calculator to work out the exact syringe units for your dose. For research use only.
