Three questions about a peptide, and a guide for each.

Is it real? Is it still intact? Does it do anything? That’s the order the questions actually arrive in, and each book answers one of them. Three free guides to start with, three paid ones when you want the whole method. No vendor names, no doses, anywhere.

Start free.

Three guides, one email, no cost. Each one is a genuine piece of the paid book it comes from — not a teaser that stops at the interesting bit.

The 12-Point COA Quick-Check

Twelve checks in the order I’d run them. Print it, keep it where lab reports land, work down it. A blank or a fail on any line means stop.

How to Read a Peptide Study Like an Engineer

The eight questions to ask of any study before you believe its headline. Once you can ask them, most of the internet gets easier to evaluate.

The Field-Guide Series.

Three books. Each stands alone; together they cover the whole chain, from the document a seller emails you to whether the molecule was ever shown to do anything.

All three together

You asked — here they are

Both of these got built because you voted for them.

This page used to carry two buttons asking which guide I should build next: reconstitution and shelf-life, or how to read a peptide study. Enough of you picked each that I built both — the first became the Stability Field Manual, the second became the method behind the Evidence Ledger. If you voted, thank you. That’s what the votes were for.
