What it's actually good for

Sleep

Research Supported

Historical RCTs showed increased delta-wave sleep and reduced sleep latency in insomniacs.

Recovery

Weak Evidence

Theoretically improves recovery via enhanced deep sleep, but direct evidence is lacking.

How it works

DSIP is a naturally occurring neuropeptide that showed promise in the 1980s for inducing delta-wave sleep and treating insomnia. Modern human clinical trials are virtually non-existent, leaving its long-term safety and efficacy profile largely unverified.

It crosses the blood-brain barrier and modulates GABAergic and glutamatergic systems to promote deep, slow-wave sleep architecture.

Safety

  • Lack of long-term human safety data.
  • Potential for morning grogginess if the dose is too high.
  • Risks associated with self-injection and unverified research chemical sources.
