| Aspect | Selank | Kisspeptin-10 |
|---|---|---|
| Mechanism | Modulates the expression of brain-derived neurotrophic factor (BDNF) and affects serotonin and norepinephrine systems. Has immunomodulatory and anxiolytic properties. | 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 | Intranasal administration: 250-500mcg 2-3 times daily. Subcutaneous: 250-500mcg daily. | Research protocols vary widely. Studies have used IV boluses of 1-10mcg/kg or subcutaneous administration. Clinical applications still being developed. |
| Administration | Most commonly administered intranasally for cognitive effects. Can also be injected subcutaneously. | IV or subcutaneous injection. Has very short half-life requiring frequent administration or continuous infusion for sustained effects. |
| Side Effects | Generally well-tolerated. Some users report mild fatigue or nasal irritation with intranasal use. | Limited data. May cause flushing, increased heart rate, and changes in libido. Generally well-tolerated in studies. |
