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

Early human signals exist, primarily from observational and pilot work — directional, not definitive.

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: directional. The next 12–24 months of registered trials will determine whether the early signal holds.

Mechanism
Mimics SNAP-25 N-terminus; competitively inhibits SNARE assembly in vitro.

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.
