Description
Premium PT-141 Nasal Spray for Advanced Research
PT-141 Nasal Spray is a research-grade intranasal peptide formulation containing PT-141 (Bremelanotide), a synthetic cyclic heptapeptide derived from the melanocortin peptide family. PT-141 has become one of the most extensively studied melanocortin receptor agonists due to its unique mechanism of action within the central nervous system. Unlike compounds that primarily target peripheral vascular pathways, PT-141 has been investigated for its interaction with melanocortin receptors (MC3R and MC4R) involved in neuroendocrine signaling and behavioral regulation.
Designed for laboratory research, PT-141 Nasal Spray provides researchers with a convenient intranasal formulation for studying peptide transport, receptor activation, and central nervous system signaling. The intranasal route is frequently investigated in neuroscience research because it allows scientists to evaluate peptide delivery through the nasal cavity while minimizing gastrointestinal degradation.
BioLongevity Labs manufactures PT-141 Nasal Spray using high-purity research materials under strict quality standards. Every production batch undergoes comprehensive third-party analytical testing to verify identity, purity, and consistency for reliable laboratory applications.

Research Benefits of PT-141 Nasal Spray
Melanocortin Receptor Research
PT-141 is widely investigated for its ability to activate melanocortin receptors, particularly MC3R and MC4R, which participate in numerous neuroendocrine and central nervous system signaling pathways. Researchers use PT-141 to better understand receptor-mediated communication and downstream intracellular signaling.
Central Nervous System Studies
Experimental research has demonstrated that PT-141 primarily acts within the central nervous system rather than directly affecting peripheral vascular tissues. This unique mechanism makes it valuable for laboratory investigations involving hypothalamic signaling, neuronal communication, and brain receptor activation.
Neurotransmitter Signaling Research
Researchers continue to investigate PT-141 for its influence on neurotransmitter systems associated with:
- Dopaminergic signaling
- Melanocortin pathways
- Neuroendocrine regulation
- Central neuronal communication
These investigations contribute to a broader understanding of neurochemical signaling networks.
GPCR Signaling Investigations
Because PT-141 activates melanocortin receptors that belong to the G protein-coupled receptor family, it serves as a valuable research tool for examining receptor activation, intracellular messenger systems, and downstream signaling cascades.
Behavioral Neuroscience Research
Laboratory models utilize PT-141 to investigate central melanocortin pathways involved in behavioral neuroscience, neuroendocrine regulation, and hypothalamic communication.
Research Effects Observed in Laboratory Studies
Experimental investigations have examined PT-141 for its potential influence on:
- MC3R receptor activation
- MC4R receptor activation
- Melanocortin signaling pathways
- Dopamine-related signaling
- GPCR activation
- cAMP intracellular signaling
- Neuroendocrine communication
- Hypothalamic neuronal activity
- Central nervous system signaling
- Receptor pharmacology
- Peptide transport following intranasal administration
These findings represent active areas of scientific investigation and should not be interpreted as established clinical outcomes.

Storage
Handling and Storage Tips:
- Keep peptides cold and away from light once received.
- For short-term use (days to weeks), refrigeration at 4°C (39°F) is acceptable.
- Lyophilized peptides are typically stable at room temperature for several weeks, making it suitable for moderate-term storage.
- For long-term storage (months to years), it’s best to freeze peptides at -80°C (-112°F). Freezing optimally preserves peptide stability for extended periods.
PT-141 for Women: The FDA-Approved Use
The FDA approved bremelanotide for acquired, generalized hypoactive sexual desire disorder (HSDD) in premenopausal women.
HSDD is more than occasional low libido. It refers to persistent low sexual desire that causes distress and is not primarily explained by relationship issues, medications, psychiatric conditions, or other medical problems.
PT-141 for Men: Off-Label Use and Clinical Evidence
It is important to state clearly that PT-141 is not FDA-approved for use in men. Its use in male sexual dysfunction is considered off-label.
That said, clinicians have explored PT-141 in men for years, particularly in cases involving:
- Erectile dysfunction (ED)
- Low libido
- Psychogenic ED
- Poor response to PDE5 inhibitors
