HMG vs Gonadorelin
| Attribute | HMG Human Menopausal Gonadotropin, menotropin | Gonadorelin GnRH |
|---|---|---|
| Category | Sexual Function & Hormones | Sexual Function & Hormones |
| Best known for | FSH/LH research and fertility protocols | GnRH-axis research |
| In plain English | HCG mimics LH only; HMG provides both LH-like and FSH activity, which is important for sperm and egg development. | Where hCG fakes the LH signal, gonadorelin pings the pituitary upstream to release real LH and FSH — keeping the entire HPG axis active. |
| How it works | Provides exogenous FSH (drives spermatogenesis and follicle development) plus LH (drives testosterone and ovulation). | Stimulates pituitary release of LH and FSH via the GnRH receptor. |
| Researchers study | Fertility, hypogonadism, and post-cycle restart protocols. | Hypogonadism, fertility, and HPG axis assessment. |
| Internet discussion | Discussed in fertility-recovery and TRT restart research circles. | Discussed as a more 'physiological' alternative to hCG. |
HMG
FSH/LH research and fertility protocols
HCG mimics LH only; HMG provides both LH-like and FSH activity, which is important for sperm and egg development.
Provides exogenous FSH (drives spermatogenesis and follicle development) plus LH (drives testosterone and ovulation).
Fertility, hypogonadism, and post-cycle restart protocols.
Discussed in fertility-recovery and TRT restart research circles.
HMG is a purified FSH/LH gonadotropin researched for fertility and full gonadal restart protocols.
Gonadorelin
GnRH-axis research
Where hCG fakes the LH signal, gonadorelin pings the pituitary upstream to release real LH and FSH — keeping the entire HPG axis active.
Stimulates pituitary release of LH and FSH via the GnRH receptor.
Hypogonadism, fertility, and HPG axis assessment.
Discussed as a more 'physiological' alternative to hCG.
Gonadorelin is synthetic GnRH researched as an upstream HPG axis stimulator.
