Confidence aggregates eight dimensions of evidence — human data, safety maturity, mechanism, clinical readiness, momentum, consistency, long-term follow-up, and translational signal. It is a measure of what is known, not a recommendation. Methodology.

Strongest supported claim

Mechanistic and preclinical evidence is suggestive; controlled human trials are not yet on the index.

Weakest / unclear

Translational confidence is limited until pre-registered human trials reproduce the preclinical signal.

Major unknowns

Interactions outside listed contraindications, long-term safety, and effect heterogeneity across age and sex are not fully resolved.

Scientific outlook

Outlook: speculative. A grade upgrade requires controlled human evidence, not additional preclinical confirmation.

Animal/in vitro data only. BPC-157 is not approved for human use in any jurisdiction.

Preclinical only; no standardized human protocol exists.

Recovery time

Preclinicalsource ↗

Animal model — not a human dosing reference. No FDA approval for BPC-157.

Animal study only; no validated human regimen.

Gut health & inflammation

Animal model. No human IBD trials. Not an approved therapy.

Preclinical only.

These are observed research regimens drawn from approved labels, clinical trials, or preclinical literature — not dosing recommendations. Suggestive, never prescriptive.

What we don't know yet
  • Long-term safety beyond reported study durations.
  • Effect size in populations under-represented in the cited trials.
  • Interactions with concomitant medications outside listed contraindications.

We surface uncertainty next to every claim. Suggestive, never prescriptive — discuss with a clinician.
