Everything this publication has published, newest first. Each piece carries its own methods box, its own limits section and a downloadable dataset; nothing is published without all three.

  1. Published 13 October 2026 · Subject: this portfolio's corpus, 77 compounds

    12 rows out of 188,556

    A peptide reference page shows a list of studies and lets a reader assume it is the literature. Counted against the queries that produced them, this portfolio's own pages carry 0.22% of what was returned. The shortfall is not a defect in one site. It is what a literature index is, and almost nobody states it.

  2. Published 13 October 2026 · Subject: this portfolio's corpus, 77 compounds, 902 records

    30 of 77 carry no human-trial record

    The tier on each compound in this corpus is a count of record types, not a verdict. Counted across all 77, it says that a catalogue presents compounds with a substantial trial literature and compounds with none in exactly the same format.

  3. Published 13 October 2026 · Subject: 902 record titles across 77 compounds

    5 flagged titles in 902

    A screen for negative findings across every record title this corpus holds returned 5 candidates out of 902. That measures the screen as much as the literature, and the first version of the screen was wrong about roughly half of what it found.

    673 hits, 431 documents

    The Federal Register is the only public record of what the US government has issued on drug compounding. Searched on the four terms the beat runs on, it returns 673 hits, 431 distinct documents, and 260 that name the FDA. The difference between those three numbers is the story.
