PT-141 is the research name used for bremelanotide, a cyclic peptide analog of alpha-melanocyte-stimulating hormone. Papers discuss it as a ligand at melanocortin receptors in central-nervous-system and neuroendocrine models. This page is a research guide. The catalog SKU is the PT-141 10mg product page.

Structure

Laboratory descriptions distinguish PT-141 from neighboring melanocortin peptides:

• A cyclic heptapeptide scaffold related to alpha-MSH, not the linear tripeptide KPV

• A different catalog identity from Melanotan I and from Melanotan II 10mg

• Sequence and ring closure that belong on the lot report and the vial label

• No shared certificate with those other SKUs

The Melanotan receptor overview covers Melanotan analogues. It is not a substitute for this PT-141 note.

Mechanisms discussed in research settings

Literature commonly places PT-141 in:

• Melanocortin-receptor binding assays, including receptors discussed in central-nervous-system models

• Peptide-receptor interaction work that compares cyclic and linear alpha-MSH analogues

• Neuroendocrine signaling maps that stay inside the assay system

• Structure-activity comparisons that do not transfer to a personal-use claim

This article does not restate human-use indications. Receptor occupancy in a paper is not an instruction.
