| Aspect | AHK-Cu | Kisspeptin-10 |
|---|---|---|
| Mechanism | The copper-binding tripeptide stimulates collagen synthesis and may promote hair follicle enlargement. Works similarly to GHK-Cu but may have distinct receptor interactions. | 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 | Topical: 0.5-2% concentration in serums for skin or scalp applications. Often combined with other growth factors for hair formulations. | Research protocols vary widely. Studies have used IV boluses of 1-10mcg/kg or subcutaneous administration. Clinical applications still being developed. |
| Administration | Topical application to skin or scalp. Can be used with microneedling for enhanced penetration. May cause temporary blue-green tint at high concentrations. | IV or subcutaneous injection. Has very short half-life requiring frequent administration or continuous infusion for sustained effects. |
| Side Effects | Generally well-tolerated. May cause skin irritation in sensitive individuals. Temporary discoloration possible. | Limited data. May cause flushing, increased heart rate, and changes in libido. Generally well-tolerated in studies. |
