BRP dosage and evidence
Written by Aaron CuhaReviewed Sep 2026
The short answer
BRP is a 12 building block peptide found at Stanford with an AI search of larger hormone proteins. In mice and minipigs, one shot cut how much they ate by up to half. It works through a different route from GLP-1 drugs. No human trial exists.
Evidence grade for BRP: Animal or lab only. The rule: only animal or lab studies on this page. No study in people yet. The sum on this page: 1 animal study, no human study. A grade counts how much has been done to people, not whether it works.

In plain English
In plain English, from Aaron
This is how I would explain it to a friend. The evidence, with the numbers, is further down the page.
BRP is a tiny peptide found at Stanford in 2025 with a computer search. In mice and minipigs, one shot cut how much they ate. It works on appetite cells in the brain, by a different route from Ozempic-type drugs. Nobody has given it to a person.
What people take it for
- Weight loss, after headlines called it natural Ozempic.
- Cutting appetite without the sick feeling of GLP-1 drugs.
What studies in people showed
There are no human studies. In lean mice and minipigs, one shot cut food intake by up to half over an hour. The animals did not act sick or avoid food, as they do on GLP-1 drugs. A company formed to develop it. No human trial is registered.
What people report
Reports, not study results
The good
- We have not collected user reports on this one yet.
The bad
- Nothing is known about its effects or safety in people.
- Products sold as BRP cannot be checked to be the real peptide.
Where these come from: Everything here comes from the one animal paper on this page. We have no user reports.
My bottom line
Interesting animal result, and that is all it is. Anything sold as BRP today is a guess in a vial. Wait for a human trial.
An opinion, not a finding. I am a coach, not a doctor.
What it has been measured to do
Animal and lab work, not yet tested in people
Real results, but from animals or cells, not people. What works in a mouse often does not work the same way in a person. Nobody can patent this, so nobody would ever earn back the cost of a study in people. That is usually why there is none.

35 of the 36 indexed goals have no study of any kind behind BRP
No study in people, animals or cells on this page reports a result for these. That does not prove BRP does nothing for them. It does mean anything you have heard about BRP and one of these did not come from a study cited here.

What is BRP?
BRP is a 12 building block peptide found at Stanford with an AI search of larger hormone proteins. In mice and minipigs, one shot cut how much they ate by up to half. It works through a different route from GLP-1 drugs. No human trial exists.
BRP was reported in the journal Nature in March 2025. A computer program predicted which small pieces get cut from larger hormone proteins, and BRP was one of them. One shot cut food intake by as much as 50% over an hour in lean mice and minipigs. The animals did not show the sick, food-avoiding behavior seen with GLP-1 drugs. It acts on appetite cells in the brain called POMC neurons. The scientists who found it started a company, Merrifield Therapeutics, to develop it. As of mid-2026 no human trial is registered. Anything sold under the name is unchecked.
How does BRP work?
It switches on appetite-control cells in the brain called POMC neurons. It does this through a different route from the GLP-1 receptor.

Nobody has tested different amounts in people
This chart would show how the effect changes as the amount goes up. For this compound, nobody has measured that in people. So we leave it empty. We will not borrow an animal chart and pretend it works the same in people.

Where to buy BRP
1 seller lists BRP in our latest read. They are ranked by trust score, then by archive rating, then by certificate tier, then by the lowest price per milligram. Archive evidence is counted before source-backed. Each path is out of 4, and the two are not added. A higher price does not raise the score. The letter is the certificate chip. 0 of them have a published certificate that names BRP.
Some seller links may pay this site when you buy through them. A payment never changes a seller's tier or rank, and no seller has a say in any page.

Common questions
Has BRP been tested in people?
Not in any study cited here. BRP is a 12 building block peptide found at Stanford with an AI search of larger hormone proteins. In mice and minipigs, one shot cut how much they ate by up to half. It works through a different route from GLP-1 drugs. No human trial exists.
What is the BRP dosage?
No human dose established. No published study on this page has given this compound to people and reported a result. 1 animal study, no human study
Is BRP FDA-approved?
Animal or lab only; nobody has asked the FDA to test it in people (no IND)
Is BRP a natural Ozempic?
That is a headline, not a finding. BRP cut appetite in animals through a different route from GLP-1 drugs. Nothing is known about what it does in people or whether it is safe.
Can I buy BRP?
No real source exists. Products sold as BRP cannot be checked to be the peptide from the Nature paper.
