Kisspeptin-10
Summary
Carnosine is an endogenous dipeptide (beta-alanine + histidine) found in high concentrations in muscle and brain. It is a potent anti-aging molecule with broad spectrum antioxidant, anti-glycation, anti-carbonylation, and metal chelating properties, making it one of the most protective naturally occurring dipeptides.
Kisspeptin-10 is the biologically active C-terminal decapeptide of kisspeptin, an endogenous regulator of the reproductive axis. It acts upstream of GnRH to potently stimulate LH and testosterone release, and plays a key role in sexual arousal and libido.
Half-Life
~1.5 minutes (rapidly hydrolyzed to beta-alanine and histidine by carnosinase in blood; tissue levels maintained via constant synthesis)
~4 minutes (rapidly degraded); longer-acting analogs like TAK-448 are in development
Admin Route
Oral, Topical
SubQ, IV
Research
Typical Dose
1,000–2,000 mg
50–500 mcg
Frequency
Once to twice daily with meals
Once daily to every other day
Key Benefits
  • Potent anti-glycation (prevents protein cross-linking/aging)
  • Broad-spectrum antioxidant in muscle and brain
  • Extends cell lifespan and protects telomeres
  • Improves muscle performance and delays fatigue (pH buffering)
  • Neuroprotective against Alzheimer's amyloid-beta
  • Wound healing acceleration
  • Anti-cataract properties (eye health)
  • Improves diabetes complications via AGE prevention
  • Chelates excess copper and zinc
  • Potently stimulates LH and testosterone
  • Enhances sexual arousal and libido
  • Activates HPG axis — upstream of GnRH
  • May improve fertility in hypogonadotropic hypogonadism
  • Increases brain activation in sexual attraction circuits
  • May restore LH pulsatility in suppressed HPG axis
Side Effects
  • Very well tolerated
  • Rare: mild GI discomfort at high doses
  • No significant adverse effects in human studies
  • Injection site reactions
  • Temporary nausea
  • Flushing
  • Elevated LH/testosterone (intended effect)
