PT-141 (10mg Vial) Dosage Protocol
Quickstart Highlights
PT-141 10mg dosage protocol is recognized for supporting healthy sexual function via on-demand subcutaneous injections.
- Typical dose is 1.75 mg (FDA-approved for HSDD) per injection
- Use on an as-needed basis (max 1 injection per 24 hours, up to 8 per month)
- Reconstitute to a practical concentration for accurate dosing
- Store lyophilized in the freezer; reconstituted in the refrigerator

Dosing & Reconstitution Guide
Educational guide for reconstitution and dosing protocol
Single Approach (2 mL = 5 mg/mL)
Dose (Per Injection) | Approx. Units | Usage / Frequency |
---|---|---|
0.5 mg (500 mcg) | 10 units | As needed; lower-end starting dose |
1.75 mg (FDA Approved) | 35 units | No more than 1 injection in 24 hrs, up to 8x/month |
2.5 mg (2,500 mcg) | 50 units | Studied upper range (use caution) |
Reconstitute with 2 mL of bacteriostatic water to create a 5 mg/mL solution (each 0.01 mL or “1 unit” ≈ 50 mcg).
- Draw 2.0 mL of bacteriostatic water into a sterile syringe.
- Inject the water slowly along the vial wall to reduce foam.
- Gently swirl—avoid vigorous shaking.
- Store the reconstituted solution at 2–8 °C (refrigerator), protected from light.
Protocol Overview
A concise summary of this on-demand regimen.
- Goal: Support healthy sexual function and desire
- Schedule: Single subcutaneous injection as needed (max 8 per month)
- Dose Range: 0.5 mg up to 2.5 mg, with 1.75 mg FDA-approved
- Reconstitution: Use ~2 ml for easy measuring (5 mg/ml concentration)
- Storage: Keep lyophilized vials frozen; refrigerate after reconstitution
Dosing Protocol
Suggested on-demand approach for effective usage.
- Weekly Dose: Not applicable; used on an as-needed basis
- Frequency: Inject subcut ~45 minutes before sexual activity
- Cycle Length: No standard cycle; do not exceed 1 injection in 24 hrs
- Maximum Dose: 2.5 mg per injection, up to 8 doses/month
- Timing: Consistency not as critical; follow as-needed guidelines
Storage Instructions
Proper storage ensures peptide integrity.
- Lyophilized: Freeze until mixing (−20°C)
- Reconstituted: Refrigerate at 2–8°C
- Avoid repeated freeze-thaw cycles
Supplies Needed
Ensure you have these on hand for safe and accurate usage.
- Peptide Vials:
• Depending on frequency and dosing (1 vial may cover multiple uses)
(Monitor usage if higher doses or more frequent injections) - Insulin Syringes:
• 1 syringe per injection - Bacteriostatic Water: 1× 30ml
- Alcohol Swabs: 1 box
Important Notes
Practical tips to enhance safety and efficacy.
- Always use new, sterile insulin syringes & rotate injection sites.
- Adhere to max 1 injection per 24 hours; do not exceed 8 doses monthly.
- Observe for adverse reactions (e.g., nausea, flushing); consult a professional if concerns arise.
- Track individual response to determine the most effective dose.
How This Works
PT-141 (Bremelanotide) is a melanocortin receptor agonist influencing sexual function via central mechanisms.
- Melanocortin Pathway: Primarily targets MC3R and MC4R receptors
- Central Effect: Modulates sexual desire through the hypothalamus
- Distinct from PDE5 inhibitors, focusing on neural pathways
Potential Benefits & Side Effects
Most users report enhanced sexual responsiveness, though individual results vary.
- FDA-approved for hypoactive sexual desire disorder (HSDD) in premenopausal women
- Potential off-label use for male sexual dysfunction
- Side effects may include nausea, headache, facial flushing
- Monitor blood pressure; mild elevations have been reported
Lifestyle Factors
Complementary strategies for maximum benefit.
- Maintain a balanced diet and healthy habits to support overall well-being
- Incorporate moderate exercise and stress-management techniques
- Prioritize adequate sleep and recovery
Injection Technique
Simple guidelines for safe daily injections.
- Clean vial rubber stopper & injection site with alcohol swabs
- Insert needle at a 45–90° angle into subcutaneous tissue
- Inject slowly & rotate sites (abdomen, thigh, etc.)
