What is DSIP?
DSIP (Delta Sleep-Inducing Peptide) is a neuropeptide that modulates sleep architecture, promoting delta wave (deep) sleep. It also influences stress hormones, pain perception, and has shown antioxidant properties. Originally isolated from rabbit cerebral venous blood.
Key Benefits & Mechanisms
Promotes deep delta wave sleep
Normalizes disrupted sleep patterns
Reduces cortisol and stress response
Pain modulating effects
Antioxidant properties
May improve GH release during sleep
Normalizes blood pressure
Research Summary
DSIP has moderate clinical evidence from European studies. Human trials show improved sleep quality and normalized sleep-wake cycles. Also studied for alcohol and opiate withdrawal. Unique mechanism distinct from traditional sleep aids.

Ipamorelin
Growth Hormone Secretagogue
Ipamorelin is a selective growth hormone secretagogue that stimulates natural GH release without significantly affecting cortisol or prolactin levels. It is considered one of the safest and most selective GHRPs available.
