Dosing & Reconstitution Guide

A practical calculator-ready setup based on the imported protocol reference. Use these values as a math starting point, then verify every entry against your own vial, diluent, and professional guidance.

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

Phase / setup Dose & frequency Volume / units
Weeks 1–2250 mcg (0.25 mg) ~7.5 units (0.075 mL)
Weeks 3–4500 mcg (0.5 mg) ~15 units (0.15 mL)
Week 1injections are <10 units; a smaller (30/50-unit) syringe improves accuracy. Draw 3.0 mL bacteriostatic water into a sterile syringe. Inject slowly against vial wall; avoid vigorous shaking. Swirl gently until dissolve...See calculator

Reference dose shown on this page: See guide.

Reconstitution Steps

  1. Confirm the vial amount, unit, and diluent amount before entering values in the calculator.
  2. Add diluent slowly down the inner wall of the vial when reconstitution is appropriate for the compound.
  3. Swirl or roll gently until dissolved; avoid shaking unless the product instructions specifically say otherwise.
  4. Label the vial with the date and concentration, then store according to the protocol and product instructions.

Supplies Needed

Keep this as a planning checklist. TNHL does not sell or verify supplies on this page, and no supplier quality claims are made here.

Peptide vial 10 mg
  • Match the label on the vial before calculating.
Diluent 2 mL
  • Use only the diluent appropriate for the compound and instructions.
Syringes U-100 or custom
  • Calculator output can be translated to syringe units.
Tracking Protocol Pal
  • Log dose dates, inventory, sites, and observations.

Protocol Overview

  • Reconstitution: Melanotan II: 3 mL; PT-141: 1 mL

Dosing Protocol

  • Reference dose shown on this page: See guide.
  • 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
  • If values change, rerun the calculator and update the protocol so future logs match the active plan.

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.

04 · Good to know

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.

05 · How it works

How This Works

The library page pairs that educational context with calculator-ready vial math, so users can understand the protocol structure and then track their own entered values in one place.

06 · Daily habits

Lifestyle Factors

  • Keep meals, training, sleep, and recovery notes in the journal so trends are easier to review.
  • Track body metrics only if they are relevant to the user's goal and approved data sources.
  • Use consistent timing and logging habits so adherence data is meaningful.

07 · What to expect

Potential Benefits & Side Effects

  • Melanotan II & PT-141 observations should be recorded conservatively: expected research endpoints, tolerability notes, injection-site reactions when applicable, sleep, appetite, energy, mood, and any adverse or unusual response.
  • This section is not a claim of therapeutic benefit.

08 · Technique

Injection Technique

Pre-injection preparation
  • Wash hands with soap and water.
  • Wipe the vial stopper and chosen site with alcohol, then let both dry.
  • Confirm the vial concentration, calculator result, and intended draw amount before loading the syringe.
Injection procedure
  • Use the route and needle technique directed by a qualified professional or product instructions.
  • For subcutaneous injections, rotate sites and inject slowly to limit leakage and irritation.
  • Do not reuse needles or syringes.
Post-injection care
  • Dispose of sharps in a puncture-resistant container.
  • Return stored items promptly to the correct temperature.
  • Log dose, site, date, time, inventory change, and any observation.
