Gonadorelin dosage chart
2 mg Vial
Gonadorelin is dosed at 50 mcg–150 mcg weekly via subcutaneous injection in educational protocols. A 2 mg vial reconstituted with bacteriostatic water yields about 1 mg/mL. This information is for research and educational use only.
- Reconstitute
- Add 2.0 mL bacteriostatic water → 1 mg/mL concentration (1000 mcg/mL).
- Typical dose range
- 50–250 mcg per injection, 2–3 times weekly.
- Easy measuring
- At 1 mg/mL, 1 unit = 0.01 mL = 10 mcg on a U‑100 insulin syringe.
- Storage
- Lyophilized: store at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles.
Route:
| Week/Phase | Dose per Injection (mcg) | Units (mL) |
|---|---|---|
| Weeks 1–2 (Initiation) | 50 mcg | 5 units (0.05 mL) |
| Weeks 3–4 (Titration) | 100 mcg | 10 units (0.10 mL) |
| Weeks 5–8 (Maintenance) | 100–150 mcg | 10–15 units (0.10–0.15 mL) |
Route:
| Week/Phase | Dose per Injection (mcg) | Units (mL) |
|---|---|---|
| Days 1–7 (Burst) | 200 mcg | 20 units (0.20 mL) |
| Days 8–14 (Taper) | 100 mcg | 10 units (0.10 mL) |
| Week 3+ (Optional Maintenance) | 100 mcg 2–3×/wk | 10 units (0.10 mL) |
Reconstitution steps
- 1Draw 2.0 mL bacteriostatic water with a sterile syringe.
- 2Inject slowly down the vial wall; avoid foaming.
- 3Gently swirl/roll until dissolved (do not shake).
- 4Label concentration (1 mg/mL) and date; refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.
Important Notes
Practical considerations for consistency and safety.
- Use new sterile insulin syringes; dispose in a sharps container.
- Rotate injection sites (abdomen, thighs, upper arms) to reduce local irritation.
- Inject slowly; wait a few seconds before withdrawing the needle.
- Document each dose, date, and site rotation to maintain consistency.
- Limit continuous daily dosing to ≤14 days to prevent receptor desensitization.
How This Works
Gonadorelin is a synthetic decapeptide identical to endogenous gonadotropin‑releasing hormone (GnRH) secreted by the hypothalamus. When administered in short, pulsatile fashion, it binds to GnRH receptors on pituitary gonadotrophs, triggering the release of luteinizing hormone (LH) and follicle‑stimulating hormone (FSH). LH stimulates Leydig cells to produce testosterone in men and triggers ovulation in women, while FSH supports spermatogenesis and ovarian follicle development. Unlike continuous GnRH agonist administration, which desensitizes receptors and suppresses gonadotropins, brief periodic dosing preserves the natural pulsatile signaling pattern.
Potential Benefits & Side Effects
Observations from clinical and preclinical literature.
- Supports endogenous testosterone production by stimulating LH release.
- May help maintain testicular volume and function during exogenous testosterone therapy.
- Promotes spermatogenesis and fertility in hypogonadotropic hypogonadism when administered in pulsatile regimens.
- Generally well tolerated; occasional mild injection‑site reactions (redness, itching, or swelling) may occur.
- Possible transient headache or flushing shortly after injection.
Lifestyle Factors
Complementary strategies for best outcomes.
- Maintain adequate sleep (7–9 hours) to support natural hormonal rhythms.
- Pair with resistance training and balanced nutrition to optimize hormonal response.
- Manage stress through relaxation techniques; chronic stress can impair HPG axis function.
- Avoid excessive alcohol and limit endocrine disruptors where possible.
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.

Gonadorelin dosage FAQs
How much bacteriostatic water do you use to reconstitute Gonadorelin?
Add 2.0 mL bacteriostatic water → 1 mg/mL concentration (1000 mcg/mL). for a 2 mg Vial vial. Add the water slowly against the inside wall of the vial and swirl — never shake — until the powder fully dissolves.
What is a typical Gonadorelin dose?
Typical dose range: 50–250 mcg per injection, 2–3 times weekly.. Figures are research reference values only.
What does the Gonadorelin route: look like?
Weeks 1–2 (Initiation) — 50 mcg — 5 units (0.05 mL); Weeks 3–4 (Titration) — 100 mcg — 10 units (0.10 mL); Weeks 5–8 (Maintenance) — 100–150 mcg — 10–15 units (0.10–0.15 mL). The full table above lists every step with matching syringe units.
What are the mixing steps for Gonadorelin?
Draw 2.0 mL bacteriostatic water with a sterile syringe. Inject slowly down the vial wall; avoid foaming. Gently swirl/roll until dissolved (do not shake).
How should reconstituted Gonadorelin be stored?
Storage: Lyophilized: store at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles..
How many insulin syringe units equal a Gonadorelin dose?
Units depend on the water volume you used. Divide your target dose by the vial concentration to get millilitres, then multiply by 100 — 1 unit on a U-100 insulin syringe is 0.01 mL. The Spartan Peptides reconstitution calculator does this conversion for you.
Is Gonadorelin approved for human use?
No. Gonadorelin is sold and referenced strictly as a research chemical. Nothing on this page is medical advice and the material is not for human consumption.
Educational and research information only. Not medical advice, not for human consumption. Values are reference figures — always verify your own math with the reconstitution calculator.
On any insulin syringe, 1 unit = 0.01 mL, so unit counts above hold across brands.
