Where our information comes from
We cite primary sources: the published paper, the trial registry entry, or the regulator’s own page. We do not cite sellers, and we do not cite a video or a post as evidence, even our own.
Every source is labelled with what was actually studied, cells, animals, or people, and how many people where that matters. A study in mice is a reason to look further, not a human result, and the label makes that visible before you click.
How a sheet is graded
Each sheet carries two separate judgments. The evidence rail places the strongest research that exists on a six-rung ladder. The status stamp states where the compound sits with the FDA. One is about the science and one is about the drug pathway, so they are never combined into a single score.
Grades are editorial calls made by the editors after reading the literature, not an automated score. When we are unsure between two rungs, we choose the lower one.
Review dates
Every sheet shows the month it was last reviewed. A review means the editors re-read the sources and checked for newer work. When a grade or status changes, the review date moves with it.
Corrections
If we get something wrong, we fix it and say so on the page, with the date. We do not quietly edit a claim after it has been read. Every sheet and note has a link to report an error, or write to thepepedit@gmail.com.
Independence and money
We do not sell peptides, recommend suppliers, or discuss dosing. We have no paid partners today. If that changes, partners will be named on our About page with how they were vetted, and a partner will never affect a grade.
