PT-141 Research Peptide (10mg)
PT-141 research peptide is a synthetic, cyclic melanocortin receptor agonist supplied as a lyophilised solid for stability and reproducibility in laboratory research. It is studied in models of neurobehavioral signalling, appetite regulation, and MC3R/MC4R activation — intended strictly for research use only.
What is the PT-141 Research Peptide?
PT-141 a cyclic melanocortin receptor agonist is a synthetic, cyclic heptapeptide and potent melanocortin receptor agonist, selectively targeting MC3R and MC4R. First characterised in studies of central melanocortin signalling [Haskell-Luevano et al., J Med Chem (1996), DOI:10.1021/jm960222h], this PT-141 research peptide is supplied as a lyophilised solid for stability and reproducibility in preclinical and in vitro research — not for human or veterinary use.
Unlike clinical formulations, NovaVitality’s PT-141 is intended exclusively for laboratory investigation of neuropeptide pathways, reward circuitry, and melanocortin-mediated physiology.

Usage and Reconstitution
The PT-141 research peptide is provided freeze-dried for long-term stability. For laboratory protocols, reconstitute using sterile bacteriostatic water (0.9% benzyl alcohol in saline) or 0.1% acetic acid in saline, depending on solubility and assay compatibility.
⚠️ Note: PT-141 may require gentle warming (≤30°C) and slow mixing for complete dissolution. Avoid vortexing to prevent aggregation of the cyclic structure.
Once reconstituted:
- Aliquot to avoid repeated freeze–thaw cycles
- Store short-term at 2–8°C (≤72 hours)
- For long-term storage: −80°C
For full guidance, refer to our [Peptide Reconstitution Protocol].

PT-141 Research Peptide: Key Investigational Pathways
PT-141 is actively studied for its role in central melanocortin modulation. Key research areas include:
- Melanocortin Receptor Signalling – Investigated in hypothalamic and limbic cell models for MC3R/MC4R activation, energy homeostasis, and satiety pathways.
- Neurobehavioral Mechanisms – Explored in rodent models of motivation, sexual behaviour, and reward circuitry (e.g., ventral tegmental area dopamine modulation).
- Neuroendocrine & Stress Response – Evaluated for interactions with CRH, ACTH, and HPA-axis regulation under controlled experimental conditions.
- Inflammatory Modulation – Studied in microglial and macrophage assays for melanocortin-mediated cytokine regulation (e.g., TNF-α, IL-6 suppression).
