Gonadorelin vs Human Growth Hormone (HGH)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Gonadorelin
Gonadorelin is a synthetic form of gonadotropin-releasing hormone (GnRH). It stimulates the pituitary to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH), supporting natural hormone production.
Full details →Human Growth Hormone (HGH)
Human Growth Hormone (somatropin) is a 191-amino acid protein identical to naturally produced GH. FDA-approved for growth hormone deficiency, Turner syndrome, and other conditions. Widely used off-label for anti-aging and performance.
Full details →Side-by-Side Comparison
| Aspect | Gonadorelin | Human Growth Hormone (HGH) |
|---|---|---|
| Mechanism | Binds to GnRH receptors in the pituitary gland, triggering pulsatile release of LH and FSH. This stimulates testicular or ovarian function and natural sex hormone production. | Binds to GH receptors throughout the body, stimulating IGF-1 production in the liver. Promotes protein synthesis, fat metabolism, and cellular regeneration across multiple tissues. |
| Typical Dosage | Men: 100-200mcg subcutaneously 2-3 times daily. Women (fertility): Per clinical protocol. HRT support: Often combined with other therapies. | Medical: 0.1-0.3mg/kg/week divided into daily doses. Anti-aging: 1-2 IU daily. Performance: 2-6 IU daily, sometimes higher. |
| Administration | Subcutaneous injection. Pulsatile administration mimics natural GnRH release patterns. Often used during or after testosterone therapy. | Subcutaneous injection, preferably at night to mimic natural pulsatile release. Rotate injection sites. Store refrigerated. |
| Side Effects | Headache, flushing, injection site reactions. In women may cause ovarian hyperstimulation. Generally well-tolerated. | Joint pain, water retention, carpal tunnel syndrome, potential insulin resistance, and acromegaly features with long-term high doses. |
