A plain-English glossary of the pharmacology, the paperwork, and the forum slang — from “bac water” to net peptide content.

Half-life, washout, and steady state — with the number cited, or an honest “no human data exists” where that is the truth.

What the FDA actually says, how to reconstitute and dose without a tenfold error, and how to tell a real certificate from a graphic.
