Enclomiphene vs Gonadorelin
Well Studied vs Extensively Studied
synergistic Researched · 95% Gonadorelin provides pulsatile GnRH stimulation to the pituitary while enclomiphene removes estrogenic negative feedback. The combination can amplify LH/FSH output beyond either agent alone.
Molecular Data
Enclomiphene Gonadorelin
Weight 405.96 Da 1,182.3 Da
Half-life ~10 hours 2-4 minutes
Chain — 10 amino acids
Type Trans-isomer of clomifene (selective estrogen receptor modulator) Decapeptide
Key Benefits
Enclomiphene
01 Raises endogenous testosterone by stimulating the HPTA axis
02 Preserves fertility and spermatogenesis (unlike exogenous testosterone)
03 No estrogenic agonist activity (unlike racemic clomifene/Clomid)
04 Oral dosing with no injections required
05 Does not suppress the HPTA or cause testicular atrophy
06 Effective for post-cycle therapy and secondary hypogonadism
07 Well-tolerated with a favorable side effect profile
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
Dosing Protocols
Enclomiphene
12.5-25mg oral daily / Once daily (morning preferred)
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
