718 gaps · 163 records · 20 fields
What we do not know, enumerated
A blank field is a bug. A named absence is a finding. These 718 say which field is empty, on which record, and why — so the shape of what we hold can be checked rather than assumed.

A gap is a claim, not a blank
Every row here asserts something: that we looked for a specific value on a specific record and did not find one that met the bar. That is different from a field nobody filled in. A blank invites you to supply the answer from the surrounding text; a named absence tells you not to. The grading rubric covers what qualifies as a source.

The reference database returned nothing
Not applicable to the compound
no pharmacokinetic study in any species on file
no study reports one, and the circulated 20-30 hours traces to supplier copy
measured in two rat studies whose numbers sit behind a paywall
the only figure published is quoted from the sponsor's investigator's brochure
phase 1 studies are published, but both full texts are paywalled and neither abstract states one
stated only in a sponsor press release, with no assay or sample size
no published human dose; the rodent doses are recorded in csvDosing and do not transfer
no primary source states a use concentration; supplier figures are not on file as primary
no stability or concentration record from a primary source; vial sizes in trade are vendor claims
a topical cosmetic ingredient supplied in solution, so the vial-and-diluent model does not apply
no controlled safety data in humans; the entry records one rodent finding and nothing else
no dedicated safety assessment of this peptide found; the tolerability figures on file belong to combination products
no approved product, and no FDA evaluation of this fragment exists; the December 2024 compounding review on file examines AOD-9604, a different molecule
no human study of hGH 176-191 or hGH 177-191 is on file; the human trial history belongs to AOD9604, a different molecule
no published study tested acetyl octapeptide-3 as the only active; both human studies on file used multi-ingredient products
no in vitro or cell experiment on this sequence found; the SNARE-interference account rests on peptides copied from other SNARE motifs
the trade name says 176-191 and the literature says 177-191; the two differ by an N-terminal phenylalanine, and which one a given vial contains is not established by any source on file
no permeation or penetration measurement for this peptide on file
not named on the 2026 Prohibited List; whether the S0 catch-all reaches it was not resolved from a WADA source
By record
163 of the 188 records are missing at least one of the eight fields tracked here. The other 25 hold all eight.
This count is taken from the records themselves rather than from what a source admitted to. It used to be the other way round, and it read as a much better number: 166 records had no source-declared gaps and showed “not on file: 0” — including one holding none of the eight fields at all.
What this ledger does not cover
These 718 are the gaps on records we publish. An earlier version of this count said 1,515, and 1,227 of those belonged to 158 rows that were never compounds — scraped seller page titles ingested as records, including HTTP error pages, order-tracking screens and blog posts. They are excluded at the export step rather than filtered here, because data that cannot be published should not reach the page layer at all.
It covers eight fields, and only those: molecular weight and formula, CAS number, PubChem CID, amino-acid sequence, SMILES, InChI and InChI key. A record holding all eight is complete by this measure and not in any wider sense — no dosing, no pharmacokinetics, and nothing about evidence, which the rubric handles separately.
Until recently it also covered only what a source had declared missing, which made it a report on our sources' paperwork rather than on our data. 166 records had no declaration and showed “not on file: 0”, one of them while holding none of the eight fields. The rows are now counted from the records themselves, which is why this number went up rather than down.
