PT-141 Reconstitution Guide
Sexual HealthDosing Calculator & Syringe Unit Conversion Tables
PT-141 (Bremelanotide) is a melanocortin receptor agonist that acts centrally on the nervous system to enhance sexual arousal. Unlike PDE5 inhibitors, it works through neural pathways rather than vascular mechanisms.
The tables below provide pre-calculated syringe draw values (U-100 insulin syringe units) for common research doses of PT-141. Find your vial size, locate your dose row, and read the units for your chosen BAC water volume.
How the Math Works
Concentration (mg/mL) = Vial mg ÷ BAC water mL
Volume to draw (mL) = Dose mg ÷ Concentration
Syringe units (U-100) = Volume mL × 100
Example: 5mg vial + 2mL BAC water = 2.5 mg/mL. For a 0.5mg dose: 0.5 ÷ 5.00 = 10.0 units. U-100 means 100 units = 1mL.
PT-141 10mg Vial — Syringe Units by BAC Water Volume
U-100 insulin syringe units (100 units = 1mL) for each research dose and BAC water amount.
| Dose (mg) | 1mL BAC | 2mL BAC | 3mL BAC | 5mL BAC |
|---|---|---|---|---|
| 0.5 mg | 5 u | 10 u | 15 u | 25 u |
| 1 mg | 10 u | 20 u | 30 u | 50 u |
| 1.75 mg | 17.5 u | 35 u | 52.5 u | 87.5 u |
| 2 mg | 20 u | 40 u | 60 u | 100 u |
Concentration at each BAC volume: 1mL → 10.00 mg/mL | 2mL → 5.00 mg/mL | 3mL → 3.33 mg/mL | 5mL → 2.00 mg/mL
Common Research Doses for PT-141
- 0.5 mg
- 1 mg
- 1.75 mg
- 2 mg
Dose ranges are derived from research literature and community protocols. Actual dosing for any research application should be determined by the supervising researcher.
Storage After Reconstitution
Refrigerate reconstituted PT-141 immediately (2–8°C / 36–46°F). Use within 30 days when refrigerated. For longer storage, freeze at −20°C; use within 6 months. Keep away from light. Do not refreeze after thawing.
