Gonadorelin dosage by administration route
Gonadorelin injectable dosage
Reported-use amounts for Gonadorelin are 100–200 mcg per administration, 1–2x daily, for 4–8 wk. Another reported subcutaneous pattern uses 100 mcg two or three times weekly during testosterone therapy, without a fixed course end date. This is different from a diagnostic bolus or a pulsatile fertility-treatment regimen and should not be presented as equivalent to either.[11][12]
Gonadorelin is synthetic GnRH and stimulates pituitary LH and FSH release. Diagnostic single doses and pulsatile fertility treatment have different administration requirements.[1][2][3][11]
Gonadorelin intranasal dosage
Reported-use amounts for Gonadorelin are ~200 mcg per administration, 6x daily, for approximately 90 days.[11]
Gonadorelin is synthetic GnRH and stimulates pituitary LH and FSH release. Diagnostic single doses and pulsatile fertility treatment have different administration requirements.[6][1][2][3][11]
Frequency and timing
Evening is a listed option for injectable use. The intranasal schedule divides six administrations across the day.[5][1][2][6][11]
Cycle length and breaks
Injectable: 4–8 wk. Intranasal: ~90 days. A standard break interval between courses is not established.[11]

Gonadorelin safety and side effects
Side effects and long-term safety
Non-clinic repeated use, long-term axis effects, and product consistency remain poorly characterized outside supervised diagnostic or fertility settings. Gonadorelin safety depends on pulsatile versus continuous GnRH exposure, fertility context, sex-steroid response, and anti-doping status.[7]
