PT-141 Nasal Spray 10mg · 10 ML

PT-141 (Bremelanotide) is a synthetic peptide derived from the melanocortin pathway.
It is studied for its effects on sexual function, libido enhancement, and central nervous system modulation of arousal, acting directly on melanocortin receptors in the brain.

Product Highlights

• Each vial contains 10 mL solution (~100 sprays)
• Each spray delivers 0.1 mL = 100 mcg PT-141
• Total PT-141 Content: 10 mg per vial
• Specialized pharmaceutical-grade nasal solution — designed for comfort and ease on the nose
• Unlike many other nasal sprays, this formula avoids irritation and dryness
• Packaged in Class A, lead-free pharmaceutical glass bottles
• Tamper/Child-Proof Cap + Orifice Reducer for integrity, sterility, and ease of use

Description

PT-141 is explored in sexual health research for its unique central mechanism of action via melanocortin receptors.
Unlike PDE5 inhibitors, it does not act on vascular pathways, making it a subject of interest in both male and female arousal studies.

Benefits

• Libido enhancement — studied for increasing sexual desire in both men and women
• Central action — works directly on the brain’s melanocortin system, unlike PDE5 inhibitors
• Versatility — explored for arousal issues independent of vascular function
• Research in both sexes — investigated for female sexual dysfunction as well as erectile function in men
• Fast-acting — studied for acute improvements in sexual readiness

Localized Effects with Nasal Spray

• Rapid uptake through the nasal mucosa
• Direct activation of central melanocortin receptors involved in arousal and libido
• Formulated with a specialized isotonic nasal vehicle to minimize irritation and dryness

What Researchers Use It For

• Mechanism: melanocortin receptor (MC3/MC4R) agonism in the hypothalamus
• Clinical trials for female sexual interest/arousal disorder (FSIAD)
• Studies in erectile dysfunction models independent of nitric oxide pathways
• Exploration of central vs. peripheral arousal mechanisms
