The compound index
Every substance an official register admits exists, in one list: 15,651 of them. Seven registers were retrieved in full and merged — not sampled, not summarised. Against each substance the index records which registers list it and exactly what status each one states.
Of those 15,651 substances, 79 carry an Etalyn grade. 15,564 do not. That gap is published rather than hidden, because a register that shows only what it has already covered is a marketing document.
What is in it
The registers, and how many entries each contributed
| Code | Register | Substances | Source |
|---|---|---|---|
| US-DRUG | openFDA — National Drug Code directory and Drugs@FDA | 7,548 | primary source |
| EU-MED | European Medicines Agency — medicines report | 1,949 | primary source |
| EU-HERB | European Medicines Agency — herbal medicines report | 176 | primary source |
| US-CSA | US DEA — Controlled Substances, alphabetical order | 581 | primary source |
| CA-NHP | Health Canada — Licensed Natural Health Products Database | 5,626 | primary source |
| EU-CLAIM | EU Register of nutrition and health claims | 1,132 | primary source |
| EU-NOVEL | EU Novel Food catalogue | 948 | primary source |
The sum exceeds 15,651 because a substance can appear in several registers at once. Merging is done on names, using only the synonyms a register itself asserts. Where two registers spell a substance differently and neither declares the link, the index keeps them apart rather than guessing — a wrong merge would put one substance’s legal status onto another.

Most substances are known to exactly one register. A substance that is a licensed supplement ingredient in Canada is usually not an authorised EU medicine, and the reverse. The regulatory picture is fragmented, and the index reproduces that fragmentation instead of flattening it.
The top row is the one worth reading twice. Those substances appear in none of the seven registers, so no authority has stated a position on any of them — and they include much of what the fitness and biohacking markets actually sell. Read them in full →
Two findings visible from the index alone
269 claims were authorised. 2,054 were not, which is 88% of everything submitted. Every refusal names the substance, the wording submitted and the EFSA opinion behind the decision. Those refusals are reproduced in the entries below, in the applicant’s own wording.
| Schedule I | 296 |
| Schedule II | 72 |
| Schedule III | 125 |
| Schedule IV | 80 |
| Schedule V | 8 |
Schedule is reproduced from the DEA list of controlled substances. It is a statement of US federal status on the date that list was retrieved, not of legality anywhere else, and not a comment on any sporting rule.

What the index does not do
- It does not state that any substance is safe, unsafe, useful or useless. Legal status is not evidence, and the two are kept in separate columns for that reason.
- It publishes no dose, no protocol, no cycle and no source of supply, anywhere, for any substance.
- It makes no statement about any sporting or anti-doping rule.
- Where Etalyn has not graded a substance, the entry says not yet graded. It does not imply an absence of evidence.
- Legal status was current when each register was retrieved and will drift. Every entry links the register it came from so the primary source can be checked.
