PT-141 / Oxytocin PRO Nasal Spray: Two Neuropeptides in One Spray
Technical Overview
PT-141 / Oxytocin PRO Nasal Spray combines two research peptides, PT-141 and Oxytocin, in a ready-to-use nasal-spray format: 20 mg of PT-141 and 10 mg of Oxytocin in a 10 mL spray bottle. The PRO formulation is shelf-stable, with a 12-month shelf life and no refrigeration required.
About PT-141
PT-141, also known as bremelanotide, is a synthetic peptide derived from the alpha-melanocyte-stimulating hormone (α-MSH) family. Researchers study it for its role in arousal through activation of melanocortin receptors, and for its broader role in neuroendocrine regulation.
About Oxytocin
Oxytocin is a synthetic form of the naturally occurring peptide hormone oxytocin. Researchers study it for its role in social bonding, emotional regulation and stress response.
Research applications
- Melanocortin signaling: how melanocortin receptor activation influences arousal and responsiveness.
- Social behavior: trust, empathy and social bonding.
- Neuroendocrine regulation: pathways linked to mood, stress response and behavior.
- Neurotransmission: brain signaling pathways related to emotional health.
The nasal-spray format lets researchers study the peptide combination under controlled laboratory conditions, at a fixed ratio and without a reconstitution step.
Why the PRO nasal spray
- Ready to use: supplied as a prepared spray, with no reconstitution step before laboratory work.
- Shelf-stable: a 12-month shelf life, with no refrigeration required.
- Labeled contents: 20/10 mg in a 10 mL spray bottle, printed on every label.
