Research material comparison: purity standards, available formats, molecular data, batch COA documentation, and regulatory status. For in vitro research use only.
Gonadorelin: AKisspeptin: C
| Attribute | Gonadorelin | Kisspeptin |
|---|---|---|
| Category | Reproductive / Hormonal | Reproductive / Hormonal |
| Evidence Rating | A — FDA Approved | C — Phase I–II Clinical Trials |
| Clinical Status | FDA-approved (Factrel for diagnostic use; Lutrepulse for pulsatile infertility treatment, now discontinued). Generic diagnostic formulation available. | Investigational / Active clinical trials in reproductive medicine |
| Mechanism | Gonadorelin binds to GnRH receptors on gonadotrope cells in the anterior pituitary gland, stimulating release of LH and FSH. When administered in a pulsatile fashion (mimicking natural hypothalamic GnRH secretion every 60–120 minutes), it maintains or restores the physiological LH/FSH surge needed f... | Kisspeptin binds to GPR54 (KISS1R) on GnRH neurons in the hypothalamus, triggering pulsatile GnRH release. This drives LH and FSH secretion from the pituitary, which increases endogenous testosterone/estrogen production. Kisspeptin works through the natural HPG axis cascade without suppressing it (u... |
