Research Overview
About PT-141
PT-141 is a unique peptide that works directly in the brain to enhance sexual desire and arousal in both men and women. Unlike other treatments, it addresses libido at the neurological level rather than just blood flow.
How It Works in Research
It works by activating melanocortin receptors in the hypothalamus (the desire center of your brain), triggering natural sexual arousal and desire. It doesn't require sexual stimulation to work - it creates genuine desire from within the brain itself.
Research Applications
Perfect for research into treating low libido, sexual dysfunction not responsive to other treatments, psychological aspects of sexual desire, and improving sexual satisfaction in both male and female subjects.
This is a simplified explanation for educational purposes. For detailed scientific information, see the Product Specifications section below.

Research Reference Parameters — Laboratory Use Only
- Initial phase: 0.5-1.0 mg as needed, 45-60 minutes before desired effect
- Standard research range: 1.0-1.5 mg as needed, titrate based on response
- Advanced research range: 1.5-2.0 mg as needed
- Recommended Timing: 1–2 hours before anticipated intimate activity, as needed.
- Use as needed basis, effects typically last 6-72 hours
For laboratory research only.
Mechanism of Action
PT-141 activates MC4R receptors in the hypothalamus and other brain regions involved in sexual function. This triggers neural pathways associated with desire, arousal, and sexual response - creating genuine physiological arousal rather than just mechanical function.
Key Research Characteristics
Central Nervous System Mechanism
PT-141 (Bremelanotide) is unique among sexual enhancement compounds - it works in the brain rather than through vascular mechanisms, addressing desire and arousal at the neurological level.
FDA-Approved for HSDD
The only peptide FDA-approved for hypoactive sexual desire disorder in premenopausal women, demonstrating clinical validation of its mechanism and efficacy.
MC4R Selective Agonist
Derived from Melanotan II but modified to increase selectivity for MC4R receptors (sexual function) while reducing MC1R activity (tanning), creating a targeted sexual enhancement profile.
Potential Benefits in Research
Female Sexual Function
- Increased sexual desire and arousal
- Improved satisfying sexual events (SSEs)
- Enhanced lubrication and genital sensation
- Reduced distress from low libido
- Male Sexual Function
- Enhanced erectile function and rigidity
- Increased sexual desire and spontaneous erections
- Improved sexual satisfaction
- Effective when psychological factors are involved
- Relationship & Quality of Life
- Improved relationship satisfaction
- Enhanced intimacy and connection
- Better overall sexual quality of life
- Works regardless of underlying cause

REFERENCE RECONSTITUTION INFORMATION
RECOMMENDED RECONSTITUTION GUIDE This guide explains how research peptides are commonly reconstituted using bacteriostatic water (BAC water), and shows how dosing volumes correspond to syringe units. Always follow sterile preparation techniques when handling research peptides.
Always follow sterile preparation techniques when handling research peptides.
⚠️ DISCLAIMER: This guide is for educational purposes only and is not medical advice. For research use only. Not for human consumption.
General Preparation
⚠️ Important: Allow product vial and BAC water to reach room temperature before reconstituting to reduce condensation uptake
- Use bacteriostatic water (BAC water) only
- Inject water slowly down the inside of the vial
- Do not shake the vial
- Gently swirl to dissolve the peptide powder
- Store refrigerated after mixing
- Use sterile technique when handling

Reference Handling Information
Reference information for laboratory handling of PT-141.
- Route
- Subcutaneous injection
- Schedule
- 45-60 minutes before anticipated intimate activity, as needed.
- Injection Sites
- Rotate injection sites (abdomen, thighs)
- Dosing
