Main Information
Gonadorelin (also known as LHRH) is a synthetic form of gonadotropin-releasing hormone (GnRH)— the hormone that triggers the pituitary gland to produce LH (luteinizing hormone) and FSH (follicle-stimulating hormone). These in turn regulate testosterone production, sperm formation, and overall reproductive function.
Key Benefits
- Stimulates natural LH and FSH secretion
- Short-acting — no long-term suppression
- Supports HPTA reactivation post-cycle
- Ideal for diagnosing pituitary or GnRH function
- Can be used in recovery or fertility enhancement
- Stackable with Clomid, HCG, or Kisspeptin
Scientific Background
Gonadorelin is a synthetic analog of Gonadotropin‑Releasing Hormone (GnRH), first identified in the 1970s as the “master switch” of reproductive hormone control. Produced naturally in the hypothalamus, GnRH signals the pituitary gland to release luteinizing hormone (LH) and follicle‑stimulating hormone (FSH)—two key messengers that regulate testosterone, estrogen, and fertility.
Why It Matters:
Unlike continuous GnRH exposure, which suppresses hormones, Gonadorelin works best in short, pulsatile doses. This method safely mimics the body’s natural rhythm, helping to:
- Boost testosterone production in men
- Support ovulation regulation in women
- Reawaken the HPG axis post‑cycle, restoring natural hormone output after suppressive compounds
From Discovery to Modern Use:
Originally developed for fertility testing and hormone replacement therapy, Gonadorelin quickly gained recognition for its precision in hormone regulation. Today, beyond clinical use, it’s valued in sports and wellness for its ability to kick‑start natural hormone production with a favorable safety profile and rapid onset of action.

Usage Instructions
- Use only under structured protocols or research supervision.
- Reconstitute vial with 1–2 ml bacteriostatic water
- Gently swirl to dissolve — do not shake
- Administer subcutaneously, ideally in the morning or pre-sleep
- Store reconstituted vial in the refrigerator (2–8 °C)
- Use within 7–10 days after mixing.
Dosage Information
HPTA Recovery / Post-Cycle Use:
- Dose: 100–150 mcg once per day
- Cycle: 7–14 days, especially after SERM use (e.g. Clomid/Nolvadex)
- Goal: Reinforce natural LH/FSH rhythm post-suppression
Diagnostic Testing (Medical / Monitoring):
- Dose: 100 mcg IV or SC
- Blood test for LH/FSH response 20–60 minutes after
- Used to assess pituitary function in suspected hypogonadism or secondary infertility
Fertility Optimization:
- Dose: 100 mcg every other day
- May be combined with HMG / HCG in assisted protocols
Important Warnings
- For research or clinical diagnostic use only
- Store unmixed vials refrigerated (2–8 °C); protect from light
- After mixing, use within 7–10 days
- Do not freeze
- Gonadorelin is non-suppressive, but should not be overused (to avoid overstimulation)
- Mild side effects may include flushing, dizziness, or temporary headache
- Always use sterile equipment and avoid stacking with suppressive agents
