About
A fact-check desk for peptide claims
Peptide Footnotes takes the claims that circulate about peptides, one sentence at a time, and checks each against the human evidence.
What the site does
Peptide marketing moves faster than peptide research. A tripeptide in a cream, a weight loss drug with large trials and a powder sold for "research use only" can all be described with the same confident words. Peptide Footnotes slows that down: each case file quotes one claim the way it is usually worded, sets it beside the published record and stamps a verdict.
The site covers skin and beauty products, weight and muscle compounds, healing and recovery peptides, brain and mood products, and the labels and paperwork that come with all of them. Approved medicines and unapproved products are kept apart, even when they share a name.
Why case files
A verdict on a single, stated claim is easier to check than a long product review. You can see what was claimed, what the studies measured, how strong they are on the five-step meter, and where the gap lies. The same format makes the files easy to compare on the verdict board and easy to correct when new evidence appears.
Who runs it
Peptide Footnotes is published by a small independent editorial desk. Files are signed by the desk rather than by named people. We will add named authors and reviewers only when real people with stated credentials put their names to the work, and we do not invent bylines or expert reviewers.
How it is funded
There are no ads, affiliate links or sponsored files, and no seller pays for coverage, placement or a better verdict. The site names no vendors and lists no prices for grey-market products. The editorial policy sets out how sources are chosen and how mistakes are corrected.
What the files are not
They are not medical advice, and they are not instructions. Where a file quotes a dose, it is the label dose of an approved medicine or the amount a study used, with its source, never a personal recommendation. Read the disclaimer and talk to a clinician about your own health.
