Nonapeptide · Cognitive & Sleep Track
What it is
DSIP — Delta Sleep-Inducing Peptide — is a nonapeptide your body produces naturally to drop you into deep, slow-wave sleep. Levels decline with age, with stress load, and with modern sleep hygiene (read: late screens, late workouts, late food). Supplementing reinforces the signal so the body remembers what real sleep feels like.
Who it’s for
The light sleeper. The 3 AM waker. The man logging eight hours but waking up like he ran a half marathon. Patients on TRT, HRT, or recovery protocols often pair DSIP with their stack to lock in the deep-sleep window where actual repair happens.
How it works
DSIP acts on the limbic system to promote slow-wave (delta) sleep — the architectural foundation of restorative rest. Unlike sedatives, it doesn’t knock you out; it nudges the natural rhythm back into shape. Most patients report deeper sleep and easier mornings within the first two weeks. Stay on track and re-evaluate at the standard 30-day check-in.
