Peptides
What is actually known about them — and which ones that is enough for.
Peptides are written about in two ways. Either as a breakthrough that hasn't caught on yet, or as a dangerous fad. Both are comfortable positions and neither helps someone who has a decision to make.
This book does a third thing: for every substance it states what is known, who it was established in, and what does not follow from it. Including the fact that for most of them the honest answer is uncomfortably short.
A dose used in a study is information about that study. It is not a dose for you.
How the evidence is graded
The same four levels as in the first volume. With peptides they fall out very differently — and that is a finding in itself.
| Level | What stands behind it | How many peptides belong here |
|---|---|---|
| A | Randomised human data on a hard outcome | A handful — and all of them are prescription medicines |
| B | Human data, but on a surrogate marker | A minority |
| C | Weak or conflicting human data | A large share of what is sold |
| D | Animals, cells or mechanism only | Most of the grey market |
The best data in this entire book belong to substances your doctor can prescribe.
How it differs from the usual guides
Every dose states where it came from. Whether it is from an approved summary of product characteristics, a human trial, an animal model, or a forum thread. That distinction is missing almost everywhere else, and it is the one that matters most.
It also covers what is not documented. Which doses circulate, where they came from, and why they may not hold.
It deals with the route of administration. Why most peptides do not work as a tablet, and what that means for the ones sold that way.
It has a practical part. What is actually in the vial, contamination, the WADA list, the legal situation, what to record for your doctor and how to raise the subject with them.

Thirteen parts
Foundations and how to read this book · Weight loss and metabolism · Muscle, strength and performance · Healing, tendons and joints · Skin and hair · Sleep · Brain, memory and mood · Immunity and inflammation · Libido · Mitochondria and energy · "Rejuvenation" and senolytics · What is sold with nothing behind it · Practical part.
Two parts deserve a special mention. Part twelve covers substances that are sold and have nothing behind them at all — not even animal data. Part thirteen is practical: purity, contamination, law, doping, and seven questions that decide whether to go ahead.
What this book is not
It is not a self-treatment manual and not a recommendation to take anything. Most substances described are not approved for human use, lack adequate safety data, and may be subject to legal, import or anti-doping restrictions.
Stating a dose used in a study is not a recommendation of that dose. This book does not replace a doctor and knows nothing about your health, your medication or your test results.
The book is written in Czech. An English edition is in preparation — if you would like to be told when it is out, write to [email protected].

Questions
Do I need the first volume first?
No, this book stands on its own. But if you have not yet sorted out blood pressure, exercise and sleep, start with the first volume. Peptides are extra money and extra risk — they only make sense once the basics are in place.
Does it contain dosing?
Yes, where it is documented — and always with a note on where the figure comes from and in whom it was established. Where it is not documented, you will be told that too. There are no invented doses in this book.
Is it a guide to what to inject?
No. It is material for making a decision and for a conversation with your doctor. The book explicitly does not tell you what to take.
