Peptide Dosages

Melanotan II (10 mg Vial) & PT-141 (10 mg Vial) Dosage Protocol

Contents

Quickstart Highlights

Stack Melanotan II and PT-141 for synergistic tanning and libido enhancement.
  • Melanotan II: 0.25–0.5 mg per injection, 2×/week for 4 weeks
  • PT-141: 1.75 mg per injection, as-needed (max 1/24 h, ≤ 8/mo)
  • Typical Melanotan II cycle: 4 weeks; PT-141 is on-demand
  • Reconstitute each vial with bacteriostatic water (max 3 mL)
  • Store the reconstituted solution at 2–8 °C (refrigerator), protected from light.

Dosing & Reconstitution Guide

Educational guide for reconstitution and daily dosing

Melanotan II (10 mg Vial): Standard/Gradual Approach

Reconstitute with 3 mL bacteriostatic water → 3.33 mg/mL. (Max 3 mL per vial.)

Week Dosage Units (mL) Frequency
Weeks 1–2 250 mcg (0.25 mg) ~7.5 units (0.075 mL)
use 30 or 50-unit syringe
2× per week
Weeks 3–4 500 mcg (0.5 mg) ~15 units (0.15 mL) 2× per week

Note: Even at 3 mL dilution, Week 1 injections are <10 units; a smaller (30/50-unit) syringe improves accuracy.

  1. Draw 3.0 mL bacteriostatic water into a sterile syringe.
  2. Inject slowly against vial wall; avoid vigorous shaking.
  3. Swirl gently until dissolved; label with date.
  4. Store the reconstituted solution at 2–8 °C (refrigerator), protected from light.

PT-141 (10 mg Vial): On-Demand Protocol

Reconstitute with 1 mL bacteriostatic water → 10 mg/mL.

 
Use Case Dosage Units (mL) Frequency
Female HSDD 1.75 mg (1750 mcg) ~18 units (0.18 mL) As needed, ≥45 min before sex
Max 1/24 h, ≤ 8/mo
Male ED (off-label) 1.0–2.0 mg 10–20 units As needed, 30–60 min before sex
Max 1/24 h, ≤ 8/mo

Alternatively, split into 1 mg (50 units) twice weekly.

  1. Draw 1.0 mL bacteriostatic water into a sterile syringe.
  2. Inject gently; swirl to dissolve; label and refrigerate.
  3. Store the reconstituted solution at 2–8 °C (refrigerator), protected from light.

Stack Administration

Administer both peptides on same day if desired—use separate syringes and injection sites; do not mix in one syringe.

  • Melanotan II injections on two consistent days/week (e.g., Mon & Thu)
  • PT-141 on-demand before sexual activity
  • Maintain injection logs to track dose and effects

Combining CJC-1295 DAC & Ipamorelin in a Stack

Administer both peptides on the same protocol day:

  • CJC-1295 DAC: 1–2 mg weekly (see approach tables)
  • Ipamorelin: 200–300 μg/day (1×–2× daily)
  • Use separate syringes and injection sites; do not mix in one vial

Supplies Needed

Materials for a 4-week Melanotan II cycle + PT-141.

  • Peptide Vials:
    • Melanotan II (10 mg Vial) – Product ID: 1049 (need 2 vials for 4-wk cycle)
    • PT-141 (10 mg Vial) – Product ID: 1044 (1 vial covers ≤ 8 doses)
  • Insulin Syringes: 30-unit & 100-unit sizes
  • Bacteriostatic Water: 1× 30 mL bottle
  • Alcohol Swabs: 1 box

Protocol Overview

4-week tanning cycle with Melanotan II plus on-demand PT-141 for libido.

  • Melanotan II: 0.25–0.5 mg/inj, 2× weekly
  • PT-141: 1.75 mg/inj, as needed (max 1/24 h, ≤ 8/mo)
  • Cycle Length: Melanotan II: 4 weeks; PT-141: flexible
  • Reconstitution: Melanotan II: 3 mL; PT-141: 1 mL

Dosing Protocol

  • Method: Subcutaneous or IM, rotate sites
  • CJC-1295: Once weekly (Monday preferred)
  • Ipamorelin: Once or twice daily (e.g., AM & bedtime)
  • Timing: Separate syringes; can align with meals or sleep
  • Duration: 4–6 weeks per cycle

Storage Instructions

Preserve potency by proper handling.

  • Lyophilized: Keep frozen until reconstitution
  • Reconstituted: Store the reconstituted solution at 2–8 °C (refrigerator), protected from light.

Important Notes

Safety and consistency tips.

  • Use new, sterile syringes each injection; rotate sites.
  • Keep detailed injection log (dose, date, effects).
  • Monitor for nausea, flushing, blood pressure changes.
  • Do not mix peptides in same syringe.

How This Works

Peptide actions underpin protocol.

  • Melanotan II: Activates MC1R → melanin synthesis (tanning), MC3/4R → libido effects.
  • PT-141: Activates MC4R in CNS → sexual arousal and desire.
  • Separate mechanisms yield complementary outcomes.

Potential Benefits & Side Effects

Research-backed outcomes with caution.

  • Enhanced baseline tan; reduced UV damage sensitivity
  • Improved sexual desire and erectile function
  • Mild side effects: nausea, facial flushing, headache
  • Monitor for pigment changes (moles), blood pressure elevations

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.)

Lifestyle Factors

Complementary strategies for best outcomes.

  • Maintain a protein-rich diet and stay hydrated
  • Engage in regular exercise; allow adequate rest
  • Manage stress and prioritize quality sleep
