| Aspect | Alpha-Defensin | Kisspeptin-10 |
|---|---|---|
| Mechanism | Insert into microbial membranes to form pores, leading to cell death. Also have immunomodulatory effects including chemotaxis of immune cells and cytokine modulation. | Binds to KISS1R receptors in the hypothalamus, stimulating GnRH neurons to release GnRH. This triggers the downstream cascade of LH, FSH, and sex hormone production. |
| Typical Dosage | Research compound - dosing varies by application. Typically studied in laboratory and early clinical research settings rather than for general use. | Research protocols vary widely. Studies have used IV boluses of 1-10mcg/kg or subcutaneous administration. Clinical applications still being developed. |
| Administration | Various routes studied including topical, local injection, and systemic administration depending on application. | IV or subcutaneous injection. Has very short half-life requiring frequent administration or continuous infusion for sustained effects. |
| Side Effects | Limited human use data. May cause local inflammation. Potential for immune activation effects. | Limited data. May cause flushing, increased heart rate, and changes in libido. Generally well-tolerated in studies. |
