Educational reference only. TNHL calculates and organizes user-entered values; it does not diagnose, prescribe, recommend doses, or replace guidance from a qualified professional.
MechanismGonadorelin is a synthetic gonadotropin-releasing hormone (GnRH) that stimulates pituitary release of LH and FSH [1] . It is used to support gonadal function and has been studied as an alternative to hCG for maintaining testicular function in men on testosterone replacement therapy [2] .
Dosing100–250 mcg once daily (gradual titration).
ReconstitutionAdd 2.0 mL diluent to a 2 mg vial.
StorageLyophilized: refrigerate at 2–8 °C (36–46 °F) or −20 °C (−4 °F) for long-term; after reconstitution, refrigerate at 2–8 °C (36–46 °F) ; do not freeze reconstituted solution.

Calculator preset

Run the vial math before tracking.

At 1.0 mg/mL, 1 unit = 10 mcg (0.01 mL); 100 mcg = 10 units and 250 mcg = 25 units on a U-100 syringe.

Quickstart Highlights

Gonadorelin is a synthetic gonadotropin-releasing hormone (GnRH) that stimulates pituitary release of LH and FSH [1] . It is used to support gonadal function and has been studied as an alternative to hCG for maintaining testicular function in men on testosterone replacement therapy [2] . This educational protocol presents a once-daily subcutaneous approach using practical dilution for accurate insulin-syringe measurements.

ReconstituteAdd 2.0 mL bacteriostatic water → 1.0 mg/mL concentration.
Reference dose100–250 mcg once daily (gradual titration).
Easy measuringAt 1.0 mg/mL, 1 unit = 10 mcg (0.01 mL); 100 mcg = 10 units and 250 mcg = 25 units on a U-100 syringe.

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.

Standard / Gradual Approach (2 mL = 1.0 mg/mL)

Phase / setup Dose & frequency Volume / units
Weeks 1–2100 mcg (0.1 mg)10 units (0.10 mL)
Weeks 3–4150 mcg (0.15 mg)15 units (0.15 mL)
Weeks 5–8200 mcg (0.2 mg)20 units (0.20 mL)
Weeks 9–12250 mcg (0.25 mg)25 units (0.25 mL)

100–250 mcg once daily (gradual titration).

Reconstitution Steps

  1. Draw 2.0 mL bacteriostatic water with a sterile syringe.
  2. Inject slowly down the vial wall; avoid foaming.
  3. Gently swirl/roll until dissolved (do not shake).
  4. Label with reconstitution date and refrigerate at 2–8 °C (36–46 °F) , protected from light.

Peptide Vials 8 weeks ≈ 5 vials
  • 12 weeks ≈ 9 vials
  • 16 weeks ≈ 12 vials
Insulin Syringes Per week: 7 syringes (1/day)
  • 8 weeks: 56 syringes
  • 12 weeks: 84 syringes
  • 16 weeks: 112 syringes
Bacteriostatic Water Use 2.0 mL per vial for reconstitution.
  • 8 weeks (5 vials): 10 mL → 1 × 10 mL bottle
  • 12 weeks (9 vials): 18 mL → 2 × 10 mL bottles
  • 16 weeks (12 vials): 24 mL → 3 × 10 mL bottles
Alcohol Swabs One for the vial stopper + one for the injection site each day.
  • Per week: 14 swabs (2/day)
  • 8 weeks: 112 swabs → recommend 2 × 100-count boxes
  • 12 weeks: 168 swabs → recommend 2 × 100-count boxes
  • 16 weeks: 224 swabs → recommend 3 × 100-count boxes

Protocol Overview

  • Goal: Support natural LH/FSH release to maintain gonadal function [1] [2] .
  • Schedule: Daily subcutaneous injections for 8–12 weeks (extend to 16 weeks if desired).
  • Dose Range: 100–250 mcg daily with gradual titration.
  • Reconstitution: 2.0 mL per 2 mg vial (1.0 mg/mL) for accurate unit measurements.
  • Storage: Lyophilized refrigerated or frozen; reconstituted refrigerated; avoid freeze-thaw cycles.

Dosing Protocol

  • Suggested daily titration approach.
  • Start: 100 mcg daily for 2 weeks to assess tolerance.
  • Increase: Progress to 150 mcg (Weeks 3–4), then 200 mcg (Weeks 5–8).
  • Target: 200–250 mcg daily as tolerated.
  • Frequency: Once per day (subcutaneous).
  • Cycle Length: 8–12 weeks; optional extension to 16 weeks with medical guidance.
  • Timing: Any consistent time; rotate injection sites daily.

Storage Instructions

  • Lyophilized: refrigerate at 2–8 °C (36–46 °F) or −20 °C (−4 °F) for long-term; after reconstitution, refrigerate at 2–8 °C (36–46 °F) ; do not freeze reconstituted solution.
  • Storage: Lyophilized refrigerated or frozen; reconstituted refrigerated; avoid freeze-thaw cycles.
  • Keep mixed and unmixed items clearly labeled so inventory and dose logs stay accurate.

04 · Good to know

Important Notes

  • Practical considerations for consistency and safety.
  • Use new sterile insulin syringes for each injection; dispose in a sharps container.
  • Rotate injection sites (abdomen at least 2 inches from navel, outer thigh, or outer upper arm) to prevent irritation or lipoatrophy [6] [7] .
  • Inject slowly; wait a few seconds before withdrawing the needle.
  • Mark the date of reconstitution on each vial and discard after 30 days.
  • Document daily dose and site rotation to maintain consistency.

05 · How it works

How This Works

Gonadorelin is a synthetic gonadotropin-releasing hormone (GnRH) that stimulates pituitary release of LH and FSH [1] .

It is used to support gonadal function and has been studied as an alternative to hCG for maintaining testicular function in men on testosterone replacement therapy [2] .

This educational protocol presents a once-daily subcutaneous approach using practical dilution for accurate insulin-syringe measurements.

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

  • Gonadorelin 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.
