About DSIP
Delta Sleep-Inducing Peptide was isolated in the 1970s from the blood of sleeping rabbits, and named for the effect it produced: an increase in delta wave activity, the slow-wave stage where physical recovery, growth hormone release and memory consolidation concentrate.
That focus on sleep quality rather than sleep onset is what distinguishes it from most sleep aids. DSIP is not researched as a sedative; the interest is in the architecture of sleep once you are in it, which is why it is usually chosen by people who fall asleep fine but wake unrefreshed. It also has a research interest in circadian regulation more broadly, which is why it appears alongside Epithalon in some protocols.
What it’s researched for
Research context, not medical advice. Everything we sell is supplied for research purposes.
Delta wave sleep
The deep, slow-wave stage where physical recovery and growth hormone release concentrate — the stage the compound is named for.
Sleep-wake regulation
Studied for circadian rhythm rather than sedation, which is why it is often paired with Epithalon in longevity protocols.
Recovery
The reason it turns up in athletic protocols: growth hormone release is largest in deep sleep, so sleep quality and recovery are the same conversation.
Reconstitution and storage
The 5mg vial with 2 mL of bacteriostatic water gives 2.5mg/mL. DSIP is dosed in the evening for obvious reasons, and protocols typically place it well before bed rather than at it. Unopened vials are stable at room temperature in transit but belong in a fridge once they arrive, and out of a parked car in a Highveld summer.
