Eighteen compounds with no approved human use anywhere — listed for completeness, with the evidence gap stated rather than papered over.
These are here because people track them and a log that refuses to record something does not stop anyone taking it — it just loses the record. What this site will not do is dress the category up. Several have no established human dosing at all, and where that is true the page says so in the dose field instead of quoting a number from a forum. Read the editorial policy for how that line is drawn.
Because the alternative is a library with a hole in it and users keeping that part of their protocol somewhere else. A complete record is worth more to a prescriber than a tidy one.
Published literature and community practice, labelled as such. Where neither gives a defensible figure the field reads "no established human dosing" rather than inventing one.
That no FDA-approved product for the compound is cited on that page, so no approved human dose is quoted. It is a statement about the page's own evidence, which makes it something you can check.
Every figure on these pages is sourced the same way — see the editorial policy for the hierarchy, and the full library for all 208 compounds.
