PT-141 10mg Dosage Protocol
Educational guide for reconstitution and administration of PT-141, a melanocortin receptor agonist studied for sexual function.
Quickstart Highlights
PT-141 dosage protocols focus on this synthetic melanocortin receptor agonist, studied for its effects on sexual arousal and function.
- Reconstitute: Add 3.0 mL bacteriostatic water → ~3.33 mg/mL concentration
- Typical protocols: 1–2 mg administered 1-2 hours before activity (subcutaneous/intranasal)
- Easy measuring: At 3.33 mg/mL, 1 unit = 0.01 mL ≈ 33.3 mcg on a U-100 insulin syringe
- Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and use within 2–4 weeks
Dosing & Reconstitution Guide
Educational guide for reconstitution and daily dosing
Subcutaneous Protocol (2 mL = 5 mg/mL)
| Phase | Daily Dose (mcg) | Units (per injection) (mL) |
|---|---|---|
| Weeks 1–8 | 500 mcg on-demand | 15 units (0.15 mL) |
| Weeks 9–12 | 1000 mcg on-demand | 30 units (0.30 mL) |
| Weeks 13–16 | 1500 mcg on-demand | 45 units (0.45 mL) |
| FDA-approved | 1750 mcg on-demand | 53 units (0.53 mL) |
Frequency: Inject once or twice daily subcutaneously. Due to the compound's plasma half-life of approximately 3.8–6.9 hours, twice-daily (BID) dosing may provide more sustained NNMT inhibition. Note: A single 10 mg vial provides only 2–4 days of research material at these doses.
Reconstitution Steps
- Remove the vial from freezer storage (−20 °C / −4 °F) and allow to equilibrate at room temperature for 15–20 minutes.
- Draw 2.0 mL bacteriostatic water with a sterile syringe.
- Inject slowly down the vial wall; avoid foaming.
- Gently swirl/roll until dissolved—solution should be clear (do not shake).
- Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light; use within 2–4 weeks.
Biological Action
PT-141 represents a synthetic peptide analog of alpha-melanocyte-stimulating hormone, designed as a selective melanocortin receptor agonist.
As a melanocortin agonist, PT-141 binds to MC4R and MC1R receptors to influence neural pathways involved in sexual arousal and motivation.
PT-141 has been studied for its effects on sexual function and motivation in research contexts.
Potential Benefits & Side Effects
Findings from sexual medicine and neuroscience research.
- Potential to support sexual arousal and function in research settings
- May assist with sexual motivation and arousal studies
- Associated with melanocortin receptor activation and neural pathways
- Generally well tolerated; occasional mild nausea or flushing
- Human safety profile remains under investigation; not approved for therapeutic use
- Long-term human safety data not established; this compound remains investigational
Injection Technique
General subcutaneous guidance from clinical best-practice resources.
- Clean the vial stopper and skin with alcohol; allow to dry.
- Pinch a skinfold; insert the needle at 45–90° into subcutaneous tissue.
- Do not aspirate for subcutaneous injections; inject slowly and steadily.
- Rotate sites systematically (abdomen, thighs, upper arms) to avoid lipohypertrophy.
- Slow injection may minimize any stinging sensation associated with the compound.
Important Notes
Practical considerations for consistency and safety.
- Use new sterile insulin syringes for each administration; dispose in a sharps container.
- Rotate injection sites (abdomen, thighs, upper arms) to reduce local irritation.
- Inject slowly; a mild stinging sensation may occur due to the quinolinium structure.
- Document daily dose and site rotation to maintain consistency.
- The 10 mg vial format is suited for short-term tolerance assessment; extended protocols require multiple vials.
