Key Benefits
Gonadorelin
01 Stimulates natural testosterone production
02 Maintains testicular function during hormone therapy
03 Supports fertility in hypogonadal conditions
04 FDA-approved for diagnostic and therapeutic use
05 Can restore LH and FSH pulsatility
06 Alternative to hCG for testicular stimulation
07 Preserves endogenous hormone production
Kisspeptin
01 Potent reproductive hormone stimulation (LH/FSH)
02 Restoration of natural testosterone production
03 Fertility enhancement
04 Sexual function support
05 Hypogonadism treatment potential
Dosing Protocols
Gonadorelin
100-200 mcg for single injections; 5-20 mcg per pulse for pulsatile therapy / 2-3 times weekly for fertility/TRT support; every 90-120 minutes for pulsatile therapy; single dose for diagnostic
Diagnostic testing 100 mcg Single injection
Fertility support 50-100 mcg 2-3x weekly
Pulsatile therapy 5-20 mcg per pulse Every 90-120 min
TRT adjunct 100-200 mcg 2-3x weekly
Kisspeptin
100-200 mcg per injection / Single dose for testing, or 2-3 times weekly (NEVER daily - causes desensitization)
Gonadotropin stimulation 100-200mcg Single dose or 2-3x weekly
Fertility support 0.4-1.0 nmol/kg (50-150mcg) As directed by physician
Sexual function (clinical) 1 nmol/kg/h 75-minute IV infusion
