DSIP, or Delta Sleep-Inducing Peptide, is a short neuropeptide first identified in early sleep research. It takes its name from its association with delta-wave activity — the deep, slow-wave stage where the body does its most restorative work overnight. It has since been studied for a broader role in circadian timing and in the signaling that links sleep to the body's stress-response system.
Rest is the substrate every other signal depends on — hormonal, metabolic, cognitive. DSIP is studied for its part in that underlying rhythm, which is why it closes the catalog: not a new instruction to the body, but a reminder of the one it already knows.
What it's used to support.
- Studied for its role in supporting delta-wave, deep-sleep architecture
- Explored for its involvement in circadian rhythm regulation
- Researched for a possible role in calming stress-response (HPA axis) signaling that can interfere with rest
- Positioned to support the body's own rest-recovery cycle, rather than sedate it into sleep
Suited to women 35+ who notice sleep has grown lighter, shorter, or more easily interrupted as hormonal patterns shift. Rest is one piece of a larger picture, best considered alongside the rest of your metabolic and hormonal health.
This compound's format and dosing are pending clinical validation and are not published generically — they are confirmed one-to-one with a licensed practitioner based on your history and goals.
Before you start.
Exact dosing and protocol are still pending clinical validation, so administration isn't standardized here. Your licensed practitioner will confirm the specific approach for you during consultation.
Response varies by person and by protocol, which is why we don't attach a timeline to it. Your practitioner can help you understand what to track and when to check back in.
Yes. Any DSIP protocol should begin with a licensed practitioner who can review your health history and confirm what's appropriate for you.
