Delta sleep-inducing peptide · sleep-modulating neuropeptide (research)
A natural off-switch for a busy brain. DSIP helps you fall asleep faster and sleep deeper, so you wake up clear instead of groggy.
DSIP — Delta Sleep-Inducing Peptide — is a natural off-switch for a busy brain. Rather than knocking you out like a sedative, it works with your sleep architecture to help you drift off faster and sleep more deeply, without the next-day hangover of sleeping pills.
Dosed about an hour before bed, responders often notice something the first few nights. One well-known quirk: it seems to lose punch after a couple of weeks — the community consensus is that mixed DSIP degrades quickly, so a fresh vial usually brings it back rather than true tolerance. It's split on whether people stick with it: poor sleepers tend to keep it around, good sleepers often don't notice much.
Animal and lab data Studied in animals and in the lab. Consistent results and a good safety record in people who use it, but not the same thing as a human trial.
0.25 mg · 3–5 nights a week
Most people start straight at 0.25mg (5 units). If you would rather ease in, run 0.1mg (2 units) first, anywhere from two to four weeks — this one is dose-sensitive for grogginess, so easing in is worth it for some people.
That is 5 units on a U-100 insulin syringe — from a 10 mg vial mixed with 2 ml of water, which gives you 5 mg/ml.
Add the water slowly down the inside of the glass and roll it — never shake it. Keep it in the fridge at 2–8 °C once mixed.
Very little. Some report grogginess if taken too late.
How long: 4 weeks–6 weeks
