§ About Melanotan I

Melanotan I is a synthetic linear alpha-MSH analogue, commonly identified in chemical databases as afamelanotide / NDP-alpha-MSH. It has been investigated in melanocortin-receptor research, including MC1R-focused structure-activity work and melanogenesis-related laboratory research.

Afamelanotide is also the established nonproprietary name associated with a licensed medicinal product in some jurisdictions. PepDirect's research material is supplied strictly as laboratory research material and is not represented as the licensed medicinal product.

§ Melanotan I and Melanotan II

Melanotan I and Melanotan II are distinct peptide identities with different structures and receptor profiles. Melanotan I is a linear alpha-MSH analogue; Melanotan II is a cyclic peptide with broader melanocortin-receptor activity. Research findings for one should not automatically be assigned to the other.

§ FAQ

What is Melanotan I?: Melanotan I is a synthetic linear alpha-MSH analogue investigated in melanocortin-receptor research. It is commonly identified in chemical databases as afamelanotide / NDP-alpha-MSH.
Is Melanotan I also called Melanotan 1?: Yes. Melanotan I and Melanotan 1 refer to the same chemical identity, the Roman-numeral and Arabic-number spellings are interchangeable.
What is another name for Melanotan I?: Chemical databases and research literature commonly identify the same peptide as afamelanotide or NDP-alpha-MSH.
Is Melanotan I the same as Melanotan II?: No. Melanotan I is a linear alpha-MSH analogue; Melanotan II is a distinct cyclic peptide with a different structure and different receptor profile. Findings for one should not automatically be assigned to the other.
What receptors are studied in Melanotan I research?: Published research primarily examines activity at the melanocortin-1 receptor (MC1R) alongside the wider melanocortin-receptor family in structure-activity work.
Is PepDirect Melanotan I intended for human use?: No. PepDirect supplies this material as a laboratory research product. It is not marketed as, or represented as, the licensed medicinal product.
How is PepDirect Melanotan I 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.
How is PepDirect Melanotan I tested?: Melanotan I is tested by HPLC to a purity of ≥ 99.5%. The current lot displayed on this page is TM-2466. A lot-specific Certificate of Analysis is published on the product page before purchase and ships in the box.
Is this intended for human use?: No. All PepDirect products are sold strictly for laboratory and research use only, and are not intended for human or veterinary use, consumption, or any clinical or diagnostic application.
How quickly does PepDirect ship?: Orders placed before 3:00 PM GMT are dispatched the same business day. Orders placed after 3:00 PM GMT are dispatched the next business day, with tracked delivery in 1-2 business days across the UK and EU. Shipping is calculated and shown at checkout based on destination.
Does PepDirect provide a Certificate of Analysis?: Yes. Every lot's COA is published on the product page before it ships, and the same PDF is included in the box.
What is your guarantee?: Same-day replacement on damaged or lost shipments, or a full refund on request, no questions asked.
