Key Findings
- DSIP increased activity of enzymes that make serotonin in the brain.
- DSIP decreased activity of enzymes that produce dopamine, particularly in the caudate nucleus.
- The enzyme changes were more pronounced in Wistar rats than in August rats.
Practical Outcomes
- The results are limited to rats and do not provide dosage, safety, or efficacy data for humans. For biohackers, this study suggests DSIP could influence mood‑related neurotransmitters, but there is no actionable protocol to apply yet. More human‑focused research would be needed before considering DSIP for sleep, mood, or performance enhancement.
Summary
A study in two types of rats found that a short‑term dose of delta‑sleep‑inducing peptide (DSIP) boosted the brain’s serotonin‑related enzyme activity while dampening dopamine‑related enzymes, especially in the caudate nucleus, and these changes were strongest in Wistar rats.
Abstract
Activity of enzymes catalyzing synthesis and degradation of serotonin and dopamine in brain structures of Wistar and August rats was measured biochemically under normal conditions and after short-term exposure to delta-sleep-inducing peptide. The effects of the test peptide manifested in activation of the serotoninergic system and inhibition of the dopaminergic system, particularly in the caudate nucleus. These changes were most pronounced in the brain of Wistar rats.
