Description
PT-141 – Libido & Sexual Function Research Peptide
PT-141 10 mg (also known as Bremelanotide) is a synthetic peptide derived from Melanotan II, designed to activate melanocortin receptors (primarily MC3R and MC4R) in the central nervous system. Unlike other compounds that act on the vascular system, PT-141 works directly on neural pathways involved in sexual arousal and desire.
It is extensively studied in both male and female sexual function research, showing potential in models of hypoactive sexual desire, erectile function, and neuroendocrine regulation of arousal.
Key Features & Research Applications
🔥 Central Arousal Activation:
Stimulates the hypothalamic melanocortin system to enhance libido and sexual motivation.
💞 Male Sexual Function Research:
Promotes erectile function via neural activation rather than vascular dilation.
🌹 Female Sexual Desire Studies:
Investigated for restoring libido and arousal in preclinical models of hypoactive sexual desire disorder (HSDD).
🧠 Neuroendocrine Research:
Influences dopamine pathways and neuropeptide signaling related to reward and pleasure.
⚡ Rapid & Reversible Action:
Produces effects quickly after administration with short biological half-life, ideal for acute-response studies.
