PT-141 Peptide Overview

PT-141 (also written PT 141 or PT141) is a synthetic peptide analog of α-melanocyte-stimulating hormone (α-MSH). The PT-141 peptide is studied in laboratory and preclinical models for its ability to activate melanocortin receptors (MC3R and MC4R), which are involved in neuroendocrine signaling, energy regulation, and vascular pathways.

Melanotan I is another melanocortin-receptor research peptide in the Medicina Labs catalog.

History

PT-141 was developed through research into melanocortin-class peptides, originally derived from modifications of Melanotan II. While Melanotan II was primarily studied for its pigmentation pathway properties, PT-141 was synthesized to focus on central target receptor activity. Since its discovery, PT-141 has been investigated in models of neuroendocrine function, vascular signaling, and peptide-receptor dynamics.

Research Findings

PT-141 has been studied in neurological, endocrine, and systemic models, with research highlighting its activity in target receptor pathways, neuroendocrine signaling, and systemic dynamics. Studies also report effects on central nervous system activity, endocrine modulation, and vascular responses in preclinical settings.

Key Areas of Research:

  • Neurological: CNS activity, signaling, pathways
  • Endocrine: Modulation, signaling dynamics
  • Systemic: Vascular responses, viability, MC3R/MC4R distribution

Together, these findings suggest experimental potential for PT-141 across neurological, endocrine, and systemic pathways. By engaging target receptor pathways and influencing neuroendocrine activity, PT-141 provides a versatile platform for research into signaling biology, systemic dynamics, and central pathway characterization in laboratory settings.

Common Questions

Purity is measured by HPLC (High-Performance Liquid Chromatography), which separates and quantifies each component in a sample. The result is reported as a percentage on the Certificate of Analysis (COA), along with the chromatogram, for every batch.
All our peptides are tested by independent third-party labs and consistently achieve 99.4%+ purity. Every product ships with a Certificate of Analysis so you can verify the exact purity of your specific batch.
