PT-141 (Bremelanotide)

PT-141 (Bremelanotide) – 10mg (Lyophilized Peptide) – For Research Use Only

PT-141 (Bremelanotide) is a synthetic peptide analog of alpha-melanocyte-stimulating hormone (α-MSH), studied for its effects on the central melanocortin receptors involved in sexual function, libido, and arousal pathways. Unlike traditional compounds that act on the vascular system, PT-141 is explored in research for its ability to influence sexual behavior and arousal through the central nervous system (CNS).

Product Details:

  • Peptide: PT-141 (Bremelanotide)

  • Purity: >98%

  • Form: Lyophilized powder

  • Quantity: 10mg per vial

  • Storage: Store at -4°F (-20°C). After reconstitution, refrigerate at 36–46°F (2–8°C) and use within 30 days.

  • Grade: For research purposes only. Not for human consumption, therapeutic, or diagnostic use.

Potential Research Applications:

  • Libido and sexual arousal pathway studies

  • Central nervous system (CNS) melanocortin receptor research

  • Neuroendocrine and behavioral response investigations

  • Sexual function and arousal mechanism modeling

For laboratory research use only. This product is not intended to diagnose, treat, cure, or prevent any disease.

Description

PT-141 is a synthetic melanocortin receptor agonist derived from the analog Melanotan II. It primarily activates the MC3R and MC4R subtypes of the melanocortin receptor family, making it a valuable compound in studies of neuropeptide signaling, central nervous system modulation, and GPCR-targeted pharmacology. PT-141 is widely utilized in preclinical research to evaluate neuroendocrine function, sexual behavior pathways, and receptor selectivity.

This 10mg formulation is research-grade and prepared under stringent quality control conditions for laboratory use. It supports studies examining ligand–receptor dynamics, signaling cascade activation, and melanocortin-linked cellular responses.

Research
  1. Melanocortin Receptor Pharmacology
    Used to investigate GPCR-mediated signaling, PT-141 allows researchers to explore agonist binding profiles, EC50 behavior, receptor desensitization, and second-messenger responses (e.g., cAMP, phospho-ERK). Its structure makes it suitable for receptor selectivity studies involving MC3R and MC4R.
  2. Central Nervous System (CNS) Pathway Exploration
    PT-141 is employed in rodent models to study hypothalamic signaling, neuromodulation, and neuroendocrine axis regulation. Experimental readouts include immediate early genes (IEGs), CREB activation, and behavioral assays linked to hypothalamic and limbic circuits.
  3. Inflammatory Signaling & Immune Modulation
    By targeting MC1R, PT-141 is also examined in immune cell models to evaluate macrophage phenotype modulation, cytokine expression profiles, and systemic inflammatory response markers.
  4. Pigmentation & Melanocyte Function
    In melanocyte-focused studies, PT-141 is used to map melanocortin pathway effects on melanin production, enzyme regulation, and UV-response signaling through cAMP/PKA/MAPK pathways.
FAQ 

Q: What does PT-141 target in research studies?
