The problem

Ten forums, ten different answers

And almost none of them tell you what is backed by evidence and what isn't.

Scattered information

Hours of forums, threads and videos, only to end up with answers that contradict each other.

Marketing in disguise

Content that overstates the benefits and stays quiet about the limits of the evidence.

Costly decisions

Unnecessary purchases and poorly built plans, all for lack of a framework to evaluate them.

The guide

One document, organized for reference

Every compound follows the same structure, so you can compare them by the same standard.

86 profiles

Across 12 sections, from weight loss to brain, sleep and bioregulators.

Evidence you can trace

A traffic light on every profile, and every citation checked against PubMed and Crossref.

Safety first

Safety principles and what hasn't been tested, stated plainly.

Practical section

Reconstitution, storage and reading a CoA, step by step.

What's actually in the PDF

Twelve sections of profiles, a practical section and the reference stacks. This is how the document you download is organized.

The fit

Who it's for

It's for you if

  • You want to understand a compound before you buy it or rule it out.
  • You already do your own research and need an organized reference to come back to.
  • You'd rather know what's proven and what isn't, even when the answer is "we don't know."

It's not for you if

  • You want a quick recipe without understanding the why.
  • You expect a compound to replace training, food and sleep.
  • You need a plan for your specific case: that's what the 1:1 consultation is for.

What's in this edition?

The 2026 edition has 249 pages and 86 profiles. It includes the brain and cognition section, 22 bioregulators, an evidence traffic light on every profile, 13 reference stacks and the 2026 regulatory update.

Do I need any background knowledge?

No. Each compound is explained starting from its mechanism, with a traffic light that tells you how well tested it is, and the guide includes a glossary. If you already know the topic, the reference stacks and the practical section are what you'll come back to most.

Does the guide tell me what to use in my case?

No. It summarizes what the published literature reports; it is not a prescription. If you want a written plan for your case, there's the 1:1 consultation.

What's the difference between the guide and the 1:1 consultation?

The guide is educational material for you to study on your own. The consultation (USD 200) is a 1:1 session where we review your case and you get a written protocol tailored to you.

Does the guide replace medical advice?

No. It's an informational resource about published literature. Make any decision about your health with a healthcare professional.

Next level

Rather go over it together?

The guide gives you the full framework. If you want a written plan for your case, with a review of your lab markers and follow-up during the first week, there's the 1:1 consultation.

  • 60-minute 1:1 call
  • Personalized written protocol
  • Review of your lab work
  • WhatsApp support for 7 days
