DSIP – Delta Sleep‑Inducing Peptide (5MG)

Sleep modulation & growth hormone linkage

• In animal models, DSIP administration was associated with increased slow-wave sleep (SWS) and increased growth hormone release following sleep deprivation.

• In a human study, DSIP reduced sleep latency and improved sleep efficiency in chronic insomniac patients vs placebo, although the statistical significance was weak and the effect modest.

• The original hypothesis that DSIP is a “sleep-promoting factor” remains only partially supported: some studies show effect, others fail to replicate strong sleep-inducing benefits.

Neuroendocrine & stress-response roles

• DSIP has been shown to impact the hypothalamic-pituitary axis and stress hormone regulation (e.g., ACTH, cortisol) in animal models.

• It exhibits neuroprotective properties: in rat stroke models, DSIP treated animals recovered motor function faster and showed reduced oxidative injury in brain tissue.

Other research observations

• Potential analgesic and anticonvulsant effects in animal studies.

• Some evidence suggests DSIP may influence body-temperature regulation, blood pressure, and metabolism, though these are less well characterised.

Summary of your found content

The content you found is largely correct:

• Sequence and origin of DSIP are accurate.

• Effects you described (sleep modulation, neuro-endocrine modulation) align with established research.
  What needed improvement:

• Emphasis on uncertainty and limited replication of sleep-promoting claims.

• Specification of molecular weight / formula should include “approximate” and highlight variation among sources.

• Clarification that many effects are from animal/in vitro models and that human data is limited.

Use-Wise Notes

• This peptide is for research use only. It is not approved for therapeutic or dietary use.

• Quality and storage: It should be supplied as high-purity lyophilised powder, stored at ≤ −20°C (or per supplier instructions), protected from moisture/light.

• When listing product details, it is advisable to include: sequence, molecular weight/approx range, intended research applications, purity specification, storage instructions, and legal disclaimer.
