What this site is
A reference covering 51 compounds across 9 families, indexed against 179 distinct claims, with ten calculators that convert numbers you already have. Every compound page answers the same three questions in the same order: what is it claimed to do, what human evidence exists for that claim, and what is its regulatory status today.
What this site is not
It does not sell peptides, link to anyone who sells peptides, or take money from anyone who does. It does not recommend doses, publish protocols, or tell you what to take. If you are deciding whether to use one of these compounds, that decision belongs with a licensed clinician who can see your history — a website cannot do that, and one that acts like it can is doing you harm.
Why the grading matters more than the entries
The single most useful thing here is not any individual profile. It is the habit of putting a grade next to a claim. Once you have read a few entries you start doing it automatically, and vendor copy stops working on you. That is the actual product.
Contact and corrections
Corrections, missing compounds and outdated regulatory status are all welcome. This field changes fast enough that some of these pages will be wrong before they are a year old.
