Here’s what you get.
- 01
A profile, in full
BPC-157 as the guide handles every compound: what was measured, in whom, and where the evidence stops.
- 02
Where do I start?
Turn a vague goal into a sentence naming the compound, the route and the outcome you want.
- 03
What to bring to a clinician
The questions that separate a real answer from a confident one. This is the page most readers print.

01 / THE RESEARCH AREAS
21 PROFILESFind your starting point.
Choose the area you want to improve, then compare the compounds and results in that section. Each numbered entry links the research to a specific goal.
Skin + hair
GHK-Cu · Zinc thymulin
Did a controlled study show a visible change?
Metabolism
Semaglutide · Tirzepatide · Tesamorelin · AOD-9604 · MOTS-c
Was the outcome weight, visceral fat, or a laboratory marker?
GH signaling + muscle
Sermorelin · CJC-1295 · Ipamorelin · Ibutamoren
Did strength or function improve when hormone levels changed?
Sleep
DSIP
Did people sleep or feel better in a controlled trial?
Immune function
Thymosin alpha-1
Which illness and clinical outcome were studied?
Cognition
Semax · Dihexa
Are there reliable human results for the same problem?
Sexual function + fertility
Bremelanotide · Kisspeptin-10 · Kisspeptin-54
Was the target desire, hormone release, or egg maturation?
Ibutamoren is a non-peptide. Dihexa is peptide-derived, with publication warnings covered in its profile. The guide separates human findings from animal and laboratory results.
Look inside first
Three real pages, before you give an email.
No sign-up to see these. They are unedited pages from the 31-page PDF, so you can judge the guide instead of a cover.

Know where to start
with peptides.
Find your goal, compare the relevant compounds, and save your shortlist. The one-page map helps you navigate; the profiles give you the results and questions to bring to your clinician.
Honest fit
Who this helps, and who should skip it.
Worth your time if
- You keep reading peptide threads and cannot tell which claims have human trials behind them.
- You want a shortlist of two or three compounds to raise with a clinician.
- You would rather see what a study measured than be told a compound "works".
Skip it if
- You want doses, sources or an administration protocol. None are in here.
- You have already decided what to take and want the decision confirmed.
Before you download
The questions people actually ask.
Is this an ad for Rebody?
No. The map covers 21 compounds, and Rebody sells a handful of them. No compound is in the guide because Rebody sells it, and the profiles say plainly where the human evidence is thin, including for compounds Rebody offers. I do run Rebody Health, and that is disclosed on the page and in the guide.
How do I know the research is real?
Every profile links its primary sources, and the last two pages list all of them with publishers and years. The evidence key on page 2 marks whether each finding came from a human trial, a human observation, an animal study or a laboratory study. Most peptide claims fall apart at exactly that distinction.
Does it tell me what to take?
It tells you what has been studied and how well. The guide carries no dosing, no sourcing and no administration instructions. The intended finish is a shortlist and a set of questions, which is the page above.
Are these legal?
U.S. regulatory status varies by compound and it moves. Each profile carries a status line, and the guide has a dedicated status-check page with the official sources. Both were rechecked on the date printed on the cover.
Why is it free?
Because I want more people running careful experiments on themselves, and because some readers eventually become Rebody Health customers. That is the whole model. No upsell arrives with the guide.
What happens to my email address?
You get the guide, then AI Biohacking, which is what I am testing and measuring on myself. You also get the revised guide whenever the research changes. One click unsubscribes and the address is never sold or shared.
