Dermorphin- Summary
- 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.
- Dermorphin is a naturally occurring heptapeptide opioid isolated from the skin of South American phyllomedusine frogs. It is one of the most potent endogenous mu-opioid receptor agonists known, approximately 30-40 times more potent than morphine by weight. Explored for pain management and fatigue modulation.
- Half-Life
- ~4 minutes (rapidly degraded); longer-acting analogs like TAK-448 are in development
- Estimated 30-60 minutes (longer than endorphins due to D-Ala)
- Admin Route
- SubQ, IV
- Subcutaneous (research), Intrathecal (research), Intranasal (research)

- Key Benefits
- 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
- Potent analgesia superior to morphine on a per-weight basis
- May reduce perception of fatigue in high-intensity activity
- Longer-lasting than endogenous opioids due to D-amino acid substitution
- Research tool for mu-opioid receptor pharmacology
