The documentation layer, gathered in one place: how to read what a supplier hands you, and where the evidence for each compound on the bench actually stops. Every piece is written from published work, with its sources printed on the page.
How to read what a supplier hands you: purity, assay, the difference between a number and a method, and what a third-party test does and does not prove.
QualityPurity is not a number a machine prints. It is the output of a specific method with specific limits — and the same vial can give different answers depending on which one you ask. Here is the method-by-method picture, from the analytical literature.

QualityThe phrase 'third-party lab tested' is a marketing phrase, not a regulated term. Here is what it has to mean to be worth anything, how to get a sample tested yourself, and the four questions that separate a real report from a sticker.
30 September 2026 · 5 min readWhere two peptides on the same shelf are not the same thing — what the published work covers for each, and where the evidence stops.
CompoundsThey are not two versions of one thing. BPC-157 is a fifteen-residue gastric peptide; TB-500 is a trade name the literature uses inconsistently for thymosin beta-4 or a fragment of it. Here is what the naming means and what the comparative evidence actually contains.
