Why this book exists.

Peptides are the fastest-moving corner of the health internet, and almost everything written about them is written by someone with something to sell you.

Every free guide is a funnel

The top search results for every compound in this book are written by the people selling it. This book carries no affiliate links and no discount codes, and nobody paid for a place in it.

The record moved in 2026

An FDA advisory committee voted, whole categories emptied, and fabricated trial registrations were planted on a public registry. The book reads the primary documents, not the headlines.

No doses, deliberately

A dose only means something if you know what is in the vial. Regulators found up to 40% of online peptide products mislabelled. The guide explains that finding and what it means for every number you read elsewhere.

What is inside

Four parts. 153 pages.

A method first, then the record: every profile built to the same fixed schema, so you can compare like with like.

Part I

How to read the evidence

The five-phrase evidence scale, what a trial can and cannot show, and the traps in peptide research: small samples, surrogate endpoints, and studies that were registered but never published.

Part II

The regulatory picture

What is actually legal, what changed in 2026 and what did not, plus the 33-compound comparison table: evidence grade, legal status and sport status, side by side.

Part III

Thirty-three profiles

Each profile follows a fixed schema: what it is, mechanism, what has been measured, evidence use by use, what we still do not know, where the marketing is ahead of the evidence, legal and sport status, and a five-axis evidence radar.

Part IV

What is actually in the vial

The mislabelling record, why grey-market products differ from trial material, and how to judge the claims any provider makes.

Where this comes from

We do not sell peptides.

That single fact is what makes this book possible. The grading can be honest because nothing in it is for sale.

Education only

We do not sell peptides and never will. No affiliate relationships, no seller partnerships, and no way to buy a place in this book.

Primary documents

Every regulatory claim is sourced from the regulator's own record: the Federal Register, FDA advisory-committee packages and the current WADA list.

418 source identifiers

Behind the profiles sit 418 numbered source identifiers. Every strong claim has a number you can chase to the original document.

Living edition

When the record moves, the book moves. Your download link always serves the current version, free, with nothing to re-buy.

Honest answers

Is this medical advice?+

No. It is a reference work about the published evidence and the legal status of thirty-three compounds. It recommends nothing, contains no doses, and tells you what the record shows and where it stops.

Does it tell me where to buy peptides?+

No, deliberately. Regulators found up to 40% of online peptide products mislabelled, and any list of sellers would be stale within months. Part IV instead teaches you how to judge the claims any provider makes. We do not sell peptides and we do not link to anyone who does. That is what protects you as a reader: nobody involved in this book earns anything from what you decide.

How do updates work?+

The guide is a living edition. Your download link is stable and always serves the current version. When the regulatory record moves or new trials report, the book is updated and every buyer gets the new edition at the same link, free.

What format is it?+

A 153-page PDF, dark theme, designed for phone, tablet and print. Works in any PDF reader. No app, no login, no DRM.

What if it is not for me?+
