Delta Sleep-Inducing Peptide
Commonly chosen for: Deep sleep
What it is
DSIP was first found in the blood of sleeping animals, which is where the name comes from. It's linked to deep, slow-wave sleep — the stage where most of your physical recovery actually happens. It's also been looked at for stress hormones and pain tolerance. The research is still early.
How it works
DSIP was first identified in the blood of sleeping animals, which is where the name comes from.
It is associated with deep, slow-wave sleep — the stage where most of your physical recovery actually happens, rather than simply adding hours of light sleep.
It has also been looked at in relation to stress hormones and pain tolerance. The research is still early.
Who it's typically for
- People who sleep enough hours but never wake up recovered.
- People whose recovery goals depend on deeper sleep.
- People who want a non-sedative approach to sleep quality.

Common side effects
Grogginess the next morning, headache and vivid dreams are reported. Human research is early, so both the benefits and the risks are less well mapped than for established sleep medications.
Who should avoid it
Not appropriate in pregnancy or breastfeeding. Discuss any sedative, sleep or psychiatric medication with your provider before combining anything.
Consult requirement
No scheduled video visit required — reviewed and prescribed by a licensed provider. Add a consult if you have a chronic condition or take other medication.
