Comparison table
| Attribute | Gonadorelin | Testosterone Cypionate |
|---|---|---|
| Full name | Gonadorelin (GnRH Analog) | Testosterone Cypionate (Depo-Testosterone) |
| Category | Hormone Replacement | Hormone Replacement |
| Status | FDA Approved | FDA Approved (Schedule III) |
| Mechanism | Binds GnRH receptors on pituitary gonadotrophs to stimulate LH and FSH release, maintaining testicular/ovarian function and natural sex hormone production. | Exogenous testosterone binds androgen receptors in muscle, bone, brain, and reproductive tissues. The cypionate ester provides slow release from the injection depot, maintaining physiologic levels between doses. |
| Molecular weight | 1182.39 Da | 412.61 Da |
| Half-life | ~10-40 minutes | ~8 days |
| Bioavailability | ~90% subcutaneous | ~100% (intramuscular) |
| Typical dose | 100-500 mcg | 100-200 mg |
| Frequency | 2-3x per week or pulsatile | Weekly or split biweekly |
| Route | Subcutaneous injection | Intramuscular or subcutaneous injection |
