Kisspeptin-10Sleep Optimization
DS5- 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.
- DS5 is a synthetic variant of the delta sleep-inducing peptide (DSIP), a nonapeptide originally isolated from rabbit cerebrospinal fluid during slow-wave sleep. Like DSIP, DS5 is explored for sleep optimization, stress modulation, and circadian rhythm normalization, with proposed improvements in potency or stability over the parent molecule.
- Half-Life
- ~4 minutes (rapidly degraded); longer-acting analogs like TAK-448 are in development
- Estimated 30-60 minutes (peptide degradation)
- Admin Route
- SubQ, IV
- Subcutaneous, 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
- Promotes delta-wave (deep) sleep and improves sleep quality
- May reduce sleep onset latency
- HPA axis modulation for stress reduction
- Non-addictive sleep support without tolerance development
- Potential circadian rhythm normalization
- Explored for insomnia, chronic stress, and PTSD-related sleep disturbance
