Sleep & Recovery

DSIP's defining research application — one of the earliest peptides studied for sleep, though its evidence base is now considered weaker than its reputation suggests.

Sleep quality improvement

Originally reported to increase deep, slow-wave sleep, though later research has not consistently reproduced this effect.

Stress resilience

Appears to influence the body's central stress-hormone axis, a more consistently supported effect than its original sleep claims.
