Wherever you start, the rules are the same
- Every factual claim on this site names its source and the kind of source it is — official, research, clinical, industry or community.
- Unknown is a real value. Records say “not stated” rather than guessing.
- Therapept does not publish recommendations, protocols or medical advice — it organizes what sources actually say.
