Independent reference & toolkit 100 compounds graded · Last reviewed June 2026

Keep the Codex independent.

No vendor money, no affiliate links, no buy-CTAs on profiles — that independence is the whole point. It just isn't free to run.

Compound Codex doesn't sell the compounds it covers and doesn't take affiliate money from anyone who does. That's what lets the grades stay honest. But hosting, the research time behind 100 compounds, and keeping every entry current cost something.

If the reference or the toolkit (bloodwork analyzer, calculator, comparisons, marker reference) has been useful, you can chip in to keep them that way. Entirely optional — there's no paywall, and there never will be on the free side.
