PT141

PT-141 (Bremelanotide) 10 mg per vial (lyophilized).

PT141 Overview

Retatrutide is an investigational triple-hormone receptor agonist designed to target metabolic pathways involved in weight management and glucose regulation. By engaging GLP-1, GIP, and glucagon receptors, it is being studied for its potential role in supporting metabolic health and body composition outcomes.

History

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

Research Findings / Overview

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, resilience

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.

Description of the imageWhat are research peptides?

Peptides are short chains of amino acids — the body’s natural signaling molecules involved in repair, metabolism, and hormone regulation. Ours are premium-grade and supplied strictly for laboratory and research use.

Our products are supplied strictly for laboratory and research purposes — not for human or animal consumption — and are intended to be handled by qualified researchers. Customers are responsible for compliance with their local regulations.

Yes. We’re a US-based research peptide lab. Every product is manufactured in the USA and independently batch-tested by Horizon Analytics (HPLC/MS), shipping with a Certificate of Analysis (COA) and full documentation on every order.

We ship worldwide from our US warehouse, and within Colombia from our Colombia warehouse. Orders process within 24 hours, ship in 24–48 hours, and typically deliver in 2–5 business days with tracking. Free shipping on orders over USD $350.

Yes — buy 3 vials of the same compound for 15% off, and first-time customers get an extra 10% off. New customers can stack both.

No prescription — these are research-use-only materials, not prescription drugs. All products arrive as lyophilized (freeze-dried) powder and require reconstitution with bacteriostatic water before research use.
