Kisspeptin vs Gonadorelin
Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research
Also: Kisspeptin-10, Kisspeptin-54
A neuropeptide that plays a critical role in initiating puberty and regulating the reproductive hormone axis. Being studied for fertility and hormonal disorders.
Also: GnRH, LHRH
A synthetic version of gonadotropin-releasing hormone. Used diagnostically and therapeutically for various reproductive and hormonal conditions.
Key Comparison Insights
- Gonadorelin is FDA approved, while Kisspeptin remains in research stages.
- Both peptides belong to the Hormonal category, suggesting similar primary applications.
- Gonadorelin has stronger research evidence (FDA Approved) compared to Kisspeptin (Human Trials).
Detailed Comparison
| Attribute | Kisspeptin | Gonadorelin |
|---|---|---|
| Category | Hormonal | Hormonal |
| FDA Status | Not FDA Approved | FDA Approved |
| Clinical Status | Pre I II III IV FDA | Pre I II III IV FDA |
| Mechanism of Action | Kisspeptin binds to the KISS1R receptor in the hypothalamus, triggering GnRH release. This initiates the hormonal cascade leading to LH and FSH release, which regulate testosterone and estrogen production. It's the master regulator of reproductive hormones. | Gonadorelin stimulates the pituitary to release LH and FSH. Pulsatile administration supports natural hormone production, while continuous administration causes desensitization and hormone suppression. Effects depend entirely on dosing pattern. |
| Common Dosing | 100-200 mcg subcutaneously once daily Once daily or every other day | 100-500 mcg 2-3x weekly 2-3x weekly |
| Administration | IV (research), subcutaneous (investigational) | IV, subcutaneous, or pulsatile pump |
| Typical Duration | Variable by protocol | Single dose (diagnostic) or ongoing (therapeutic) |
| Best Time to Take | Morning or as directed | Morning or as clinically directed |
Possible Side Effects May vary by individual |

|
| Research Summary | Research shows kisspeptin administration can restore reproductive function in hypothalamic amenorrhea. Studies demonstrate effects on testosterone production and potential for fertility treatment. Being investigated for hypogonadism and reproductive disorders. | FDA approved for diagnostic testing of pituitary function. Used to stimulate testosterone production when given in pulses. Continuous use leads to chemical castration effect used in prostate cancer and endometriosis. |
