- Kisspeptin-10
- GnRH pulse activation via GPR54 receptor binding
- 100–200mcg twice daily, pulsatile
- ~28 minutes
- LH rise within 90 minutes; subjective libido improvement 10–14 days
- Best option for libido protocols. Short half-life allows pulsatile dosing that preserves receptor sensitivity. Requires strict timing discipline.
- Kisspeptin-54
- Same GPR54 binding, longer peptide chain
- 200–500mcg once daily
- ~2 hours
- Slower onset, similar endpoint
- Longer half-life makes pulsatile dosing impractical. More suitable for fertility protocols than acute libido restoration.
- PT-141 (Bremelanotide)
- Melanocortin receptor agonist (MC4R). Central nervous system arousal
- 1–2mg as needed, 45 min pre-activity
- 2.7 hours
- Arousal within 30–60 minutes, peaks at 2–3 hours
- Works via different pathway (CNS arousal vs hormonal cascade). Faster subjective effect but does not address underlying hormonal dysfunction.
- Gonadorelin (synthetic GnRH)
- Direct GnRH receptor agonist
- 100mcg pulsatile every 90 minutes via pump
- 2–4 minutes
- Requires continuous infusion for effect
- Impractical for self-administration. Used clinically for hypogonadotropic hypogonadism, not general libido protocols.
