DSIP in insomnia.
Schneider-Helmert. D D
Key Findings
- A single pre‑sleep injection of 25 nmol/kg DSIP improves sleep quality.
- Repeated nightly doses build up effect, normalizing sleep after about four administrations.
- Morning injections boost daytime activity and still improve night sleep; twice‑daily dosing offers no extra gain.
- Higher doses helped a patient with insomnia linked to organic brain disease.
Practical Outcomes
- For biohackers, a practical protocol could be a 25 nmol/kg DSIP injection taken shortly before bed, repeated for several nights to enhance the benefit. If daytime alertness is also desired, a morning dose can be added, but avoid splitting the dose into two daily administrations. Adjust upward only if standard dosing fails, and monitor individual response.
Summary
Research shows that giving delta sleep‑inducing peptide (DSIP) as a single shot of about 25 nmol per kilogram right before bedtime can improve sleep, and taking it for a few nights in a row may make the effect stronger. Morning doses also help night sleep while boosting daytime energy, but taking it twice a day doesn’t add extra benefit. One severe insomnia case improved with higher doses.
Abstract
This paper summarizes different investigations into effects of delta sleep-inducing peptide (DSIP) injections on insomnia. Two different studies showed improvement of sleep following single injections of 25 nmol/kg b.w. before sleep. Repeated administrations indicated a buildup with normalization of sleep structure after four administrations. Repeated injections in the morning - besides increasing daytime activity - still had a strong positive effect on night sleep, but not so two doses daily. A case of insomnia in organic brain disease responded well to higher doses. The results are discussed as to the mode of action of DSIP and its possible therapeutic use in insomnia.
