Compare peptides

Two to four compounds, field by field: identity, United States regulatory status, and what kinds of documents are on file. The table records differences. It does not rank them.

No winner, no score, no recommendation. Counts describe how many documents of each kind Therapept has indexed — not how well a compound works, and not how much has been published overall.

Every identity and regulatory value above is taken from the compound’s record, where its sources are listed. Evidence counts are derived from the published evidence file at build time. A missing class means no document of that kind is indexed — not that none exists.
