§ About Melanotan II

Melanotan II is a synthetic cyclic melanocortin peptide and alpha-MSH analogue. Published research has investigated its pharmacology at melanocortin receptors including MC1R, MC3R and MC4R.

Findings from melanocortin-receptor research should not be translated into human-use claims for PepDirect research material. This product is supplied exclusively for laboratory research use.

§ Melanotan II and PT-141

PT-141 (bremelanotide) emerged from related melanocortin-analogue research but is a distinct compound with its own chemical identity and pharmacology. The two should not be treated as interchangeable.

§ FAQ

What is Melanotan II?: Melanotan II is a synthetic cyclic melanocortin peptide and alpha-MSH analogue investigated in melanocortin-receptor research.
Is Melanotan II also called Melanotan 2?: Yes. Melanotan II and Melanotan 2 refer to the same chemical identity.
What receptors are studied in Melanotan II research?: Published research examines activity across the melanocortin-receptor family including MC1R, MC3R and MC4R.
Is Melanotan II the same as Melanotan I?: No. Melanotan II is a distinct cyclic peptide; Melanotan I is a linear alpha-MSH analogue. Their structures and receptor profiles differ, and research findings should not be transferred between them.
Is Melanotan II the same as PT-141?: No. PT-141 (bremelanotide) emerged from related melanocortin-analogue research but has its own distinct chemical identity and pharmacology.
How is PepDirect Melanotan II tested?: Every lot is supplied with lot-specific documentation. HPLC purity is reported on the product hero and full identity information is captured in the lot Certificate of Analysis.
Is this intended for human use?: No. PepDirect supplies Melanotan II as a laboratory research product only. It is not marketed as a medicine, food supplement or product for human or veterinary use.
How is PepDirect Melanotan II tested?: Melanotan II is tested by HPLC to a purity of ≥ 99.5%. The current lot displayed on this page is TM-2409. A lot-specific Certificate of Analysis is published on the product page before purchase and ships in the box.
