Corrections policy
How to flag an error in the library and what happens once it is reported.
Last reviewed 24 Jul 2026
Report an error
If a library entry misstates a compound's evidence position, cites a source that does not say what it is credited with saying, or simply looks wrong, say so: health@trainnorthlabs.com. Include the compound name and, if you have one, a link to the source that supports the correction.
What happens next
A reported error is checked against the source material behind the entry. If the entry is wrong, it is corrected and the last reviewed date for that page is updated. If the entry is right and the report was based on a misunderstanding, a reply explains why the grade stands.
What this site does not do
Corrections are not accepted on commercial grounds: a supplier relationship, a discount, or a sales argument is never a reason to move a compound's evidence grade. Only evidence moves it.
