PT-141 10MG Research Overview

PT-141 is a synthetic cyclic heptapeptide melanocortin receptor agonist, developed from Melanotan II as its active metabolite-like analog. PT-141 10MG is supplied for qualified in-vitro laboratory research and analytical use only.

Compound profile

  • Compound class: Cyclic heptapeptide melanocortin receptor agonist
  • Molecular weight: ≈ 1025.2 g/mol
  • CAS number: 189691-06-3
  • Receptors: MC3R and MC4R (central melanocortin receptors)
  • Form: Lyophilized powder in a sealed vial
  • Testing: Third-party HPLC purity and identity, batch-matched COA

Research context

PT-141 acts mainly on the central MC3 and MC4 receptors, and is studied in hypothalamic melanocortin signaling, neuroendocrine and behavior-related research models. Compared with Melanotan II, it lacks the C-terminal amide, which shifts its receptor-activity profile and is a common point of comparison in melanocortin research.

Storage and handling

Store unopened lyophilized vials sealed and protected from light — at −20 °C for long-term storage, or 2–8 °C for short-term use. Once reconstituted, keep refrigerated at 2–8 °C, minimize freeze–thaw cycles and rely on your laboratory’s own validated stability data.

Quality and documentation

Every lot is third-party tested, and the Certificate of Analysis is matched to the exact batch you receive — look it up any time on the COA page. Browse more Melanocortin Research, or see related compounds: MTII 10MG, KPV 10MG.
