PT-141 (Bremelanotide)
PT-141 (Bremelanotide) is a melanocortin receptor agonist acting on the central nervous system, investigated for pro-sexual effects and arousal enhancement in both male and female research models.
Dosage protocol (U-100 insulin syringe)
| Dose level | Dose | Frequency |
|---|---|---|
| Beginner | 0.5 mg (50 units) | As needed — max 1x per 24 hours |
| Standard | 1 mg (100 units) | As needed — max 1x per 24 hours |
| Advanced | 2 mg (200 units) | As needed — max 1x per 24 hours |
Common research protocol: 0.5–2 mg injected subcutaneously, typically 30–45 minutes before the study window. Do not exceed one administration in any 24-hour period. Adjust based on individual response and study design.
How often to use
- As needed — at most once in any 24-hour period.
- Allow at least 24 hours between administrations.
How to administer
- Reconstitute with bacteriostatic water.
- Draw your dose with an insulin syringe.

- Do not freeze.
- Protect from light.
- Use within 90 days after first puncture.
- Keep the vial tightly sealed when not in use.
Common use
- Studied for sexual dysfunction research
- Acts on central melanocortin receptors
- Investigated for arousal enhancement
- Studied for both male and female applications
Important
- For research use only – not for human or veterinary use.
- Not for resale or distribution.
- Keep out of reach of children.
- Consult with a healthcare professional before use.
- Discontinue use if adverse reactions occur.

How to inject
Reading your syringe
Doses on this site are written in units. A standard U-100 insulin syringe holds 100 units (1 mL). Each small line is 1 unit; each long numbered line is 10 units. Draw to the line where the black plunger tip stops.
Subcutaneous injection sites
Most peptides are injected subcutaneously — into the fat just under the skin. Common sites are the abdomen (avoid 2 inches around the navel), front outer thigh, outer upper arm, upper outer hip, or lower back. Clean the area, rotate sites, and use a new needle each time.
