**Our rule 01**

We sell nothing

No vendor links, no affiliate codes, no sponsors who sell the compounds we cover.

**Our rule 02**

We don't give doses

Most of these have no tested human dose. We tell you what to ask a prescriber instead.

**Our rule 03**

We show our corrections

Every page has a public changelog. When we get something wrong, we say so on the page.
