EVIDENCE TAKEAWAY

The short answer.

DSIP's therapeutic reputation rests on very small historical studies and uncertain physiology, not on a modern clinical development program.

WHAT IS DSIP?

Start with identity.

A small endogenous research peptide associated with sleep physiology, with uncertain therapeutic relevance.

HUMAN VS PRECLINICAL

What evidence exists for DSIP?

HUMAN EVIDENCE
1/5 · Very small historical studies

Human sleep studies were tiny and conducted decades ago; they do not establish a modern therapeutic evidence base.

PRECLINICAL EVIDENCE
2/5 · Uncertain physiology

Historical laboratory research explored sleep and stress physiology, with unresolved questions about identity and mechanism.

RESEARCH INTENT

What is DSIP being studied for?

Current source-backed research areas include the topics below. Inclusion means the area is being investigated; it does not establish a treatment benefit.

  • 01Sleep physiology
  • 02Stress response
  • 03Neuropeptide identity
  • 04Electroencephalography

U.S. REGULATORY STATUS

Is DSIP FDA approved?

No FDA-approved DSIP drug product; FDA enforcement records have described DSIP products as unapproved new drugs.

SPORT STATUS

Is DSIP prohibited in sport?

Not specifically named in the 2026 WADA List; athletes should verify current status and product contents.

Anti-doping rules and product ingredients can change. Athletes should verify the current official list and the exact product before making a real decision.

EVIDENCE LIMITS

What can the current record not establish?
