🔬 Science & Mechanism
Kisspeptin is a naturally occurring peptide critical for reproductive health.
- Triggers release of GnRH → LH & FSH, activating the reproductive hormone axis.
- Human trials show increased activity in brain areas linked to sexual arousal.
- Plays a role in fertility, puberty, and reproductive signaling.
📊 Clinical Evidence
- A landmark UK study found kisspeptin enhanced sexual arousal brain activity in men (measured via fMRI).
- Other trials suggest Kisspeptin could improve fertility outcomes via enhanced HPG axis stimulation.
- Emerging evidence positions it as a potential arousal-enhancing peptide for both men and women.
💉 Dosing Guide (Educational)
Reported Protocols:
- 100–200 mcg subcutaneous, 1–2× weekly.
- Some studies used higher, short-term doses in research settings.
- Often cycled in 4–8 week blocks.
💧 Reconstitution (5 mg vial + 2 mL BAC water)
- Final concentration = 2.5 mg/mL
- On insulin syringe (100 units = 1 mL): 25 mcg per unit
| Desired Dose | Volume (mL) | Syringe Units |
| 100 mcg | 0.04 mL | 4 units |
| 200 mcg | 0.08 mL | 8 units |
| 500 mcg | 0.20 mL | 20 units |
🧊 Storage
- Store lyophilized vials refrigerated (2–8 °C).
- After reconstitution, refrigerate and use within 30 days.
- Protect from light.
❓ FAQ
How is Kisspeptin different from PT-141?
Kisspeptin primarily affects hormone signaling and arousal brain centers, while PT-141 drives sexual motivationdirectly via melanocortin receptors.
Can it help with fertility?
Yes — kisspeptin stimulates GnRH → LH/FSH release, critical in fertility pathways.
Is it safe for both men and women?
Yes — early human studies tested Kisspeptin in both sexes with promising results.
