Kisspeptin-10- Summary
- Glutathione is the body's master endogenous antioxidant tripeptide, composed of glutamate, cysteine, and glycine. It neutralizes reactive oxygen species, supports detoxification in the liver, recycles other antioxidants (vitamins C and E), and plays a central role in immune function, DNA repair, and cellular redox balance.
- 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
- Minutes to hours depending on route; IV half-life approximately 10-30 minutes
- ~4 minutes (rapidly degraded); longer-acting analogs like TAK-448 are in development
- Admin Route
- Oral (liposomal preferred), Sublingual, Intravenous, Nebulized/inhaled, Topical
- SubQ, IV

- Typical Dose
- 250-1000 mg per day
- 50–500 mcg
- Frequency
- Once or twice daily
- Once daily to every other day
- Key Benefits
- Primary endogenous antioxidant and free radical scavenger
- Supports hepatic detoxification of xenobiotics and heavy metals
- Recycles vitamins C and E to maintain antioxidant network
- Modulates immune function and T-cell activity
- Skin brightening via inhibition of tyrosinase (IV/topical routes)
- Neuroprotective in oxidative stress-related conditions
- Mitochondrial protection and energy metabolism support
- 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
- Oral bioavailability is limited (largely hydrolyzed in gut); liposomal or sublingual forms preferred
- IV administration: rare allergic reactions, vein irritation
- High-dose supplementation may cause zinc depletion over time
- Inhaled glutathione may trigger bronchoconstriction in asthmatics
- Injection site reactions
- Temporary nausea
- Flushing
- Elevated LH/testosterone (intended effect)
