ACTH 1-39 vs Gonadorelin
| Attribute | ACTH 1-39 Corticotropin, full-length ACTH | Gonadorelin GnRH |
|---|---|---|
| Category | Sexual Function & Hormones | Sexual Function & Hormones |
| Best known for | HPA axis and adrenal cortisol research | GnRH-axis research |
| In plain English | It's the body's natural 'press the cortisol button' hormone. | 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 | Binds the MC2 receptor on the adrenal cortex, driving cortisol, DHEA, and aldosterone production. | Stimulates pituitary release of LH and FSH via the GnRH receptor. |
| Researchers study | Adrenal insufficiency, infantile spasms, and HPA axis function. | Hypogonadism, fertility, and HPG axis assessment. |
| Internet discussion | Niche; discussed in adrenal-fatigue and endocrine research circles. | Discussed as a more 'physiological' alternative to hCG. |
ACTH 1-39
HPA axis and adrenal cortisol research
It's the body's natural 'press the cortisol button' hormone.
Binds the MC2 receptor on the adrenal cortex, driving cortisol, DHEA, and aldosterone production.
Adrenal insufficiency, infantile spasms, and HPA axis function.
Niche; discussed in adrenal-fatigue and endocrine research circles.
ACTH 1-39 is the full-length corticotropin researched for adrenal cortisol release and HPA axis study.
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.
