Compound library

One page per compound: what it is, what the evidence shows, its regulatory status on the day it was verified, the published half-life STACK uses (or a plain statement that no human value exists), reported side effects, storage, and what STACK tracks. Every claim is cited. Nothing here is dosing guidance.
