Mechanism of action
Kisspeptin activates KISS1 receptors upstream of hypothalamic GnRH signaling, influencing LH/FSH pulsatility and reproductive-axis regulation.
Half-life & pharmacokinetics
Half-life: Short acting.
Human pharmacokinetics are not standardized. Treat exposure as short acting unless compound-specific data or formal formulation labeling indicates otherwise.
Research dosing reference
100-500 mcg daily or pulse-style reproductive-axis research exposure.
Dose interpretation (U-100 units)
| Target dose | U-100 units |
|---|---|
| 100 mcg | 2 units |
| 250 mcg | 5 units |
| 500 mcg | 10 units |
Units are concentration-specific - confirm against your actual reconstitution volume.
Reconstitution & concentration
| Vial | Preferred reconstitution | Final concentration |
|---|---|---|
| 10 mg | 2 mL BAC Water | 0.050 mg/unit |
Injection timing
Often timed based on reproductive-axis objective; consistency and pulse logic matter.
Beginner escalation
Begin low and assess endocrine response before increasing frequency or dose.
Side-effect mitigation
Monitor mood, libido changes, flushing, headache, or endocrine-axis symptoms.
Stack compatibility
Avoid stacking with multiple HPG-axis agents without lab interpretation.
Storage & stability
Lyophilized: refrigerated or controlled cool storage. Reconstituted: refrigerated, protected from heat/light, and handled aseptically.
Protocol duration & reassessment
Use objective-driven, marker-aware courses. Reassess endocrine, mood, libido, blood-pressure, or target-symptom response before repeating or escalating.
Frequently asked questions
What is Kisspeptin and how does it work?
Kisspeptin activates KISS1 receptors upstream of hypothalamic GnRH signaling, influencing LH/FSH pulsatility and reproductive-axis regulation.
What is the half-life of Kisspeptin?
Kisspeptin: Short acting. Human pharmacokinetics are not standardized. Treat exposure as short acting unless compound-specific data or formal formulation labeling indicates otherwise.
How is Kisspeptin reconstituted for research?
Preferred reconstitution for the 10 mg vial is 2 mL BAC Water, giving 0.050 mg/unit. Always confirm concentration math before any use. Research use only.
Is Kisspeptin FDA approved?
No. Kisspeptin is an investigational research-use-only compound - not for human or animal consumption and not FDA approved.
