Cardiogen Peptide: What It Is and What the Research Shows
Cardiogen peptide is AEDR (Ala-Glu-Asp-Arg), a four amino acid peptide listed in a 2022 paper as a cardioprotector. A review by the group that developed it reports that rats given AEDR after a heart attack had three times fewer deaths. No study in people was found.

Short answer
- Is cardiogen good for the heart?
- In rats, a review reports fewer deaths after a heart attack. In people, nobody knows yet.
- Where does that result come from?
- A 2022 review describing earlier work by the same group. The original rat paper was not read for this page.
- Is it an approved heart drug?
- No. No FDA label or tested human dose was found. The FDA label you may see is for CardioGen-82, an unrelated scan product.

The Rat Heart Attack Result
This is the best known cardiogen result. Researchers caused heart attacks in rats by tying off a coronary artery. Rats then given AEDR had a threefold drop in deaths compared with the control group.
The review reports two more findings in those rats:
- Smaller zones of dead heart tissue.
- Better kept glycogen, the stored sugar in heart muscle.
Note on the source: a review by the group that developed AEDR describes this rat work. We did not read the original paper. So the number of rats, the dose and the methods are not given here.
Where the Heart Link Comes From
The heart link starts with chemistry. A 2022 review says AEDR was found in a polypeptide extract of the heart. The team used highly sensitive chromato-mass spectrometry to detect it.
The lab-made version is called cardiogen. Its four amino acids are alanine, glutamic acid, aspartic acid and arginine. A 2022 transport paper lists it with the role "cardioprotector". That is a label in a table, not a test result.

How Far the Cardiogen Evidence Goes
The evidence stops one step short of people. The ladder runs from the weakest kind of study to the strongest.
| Level | Any studies? | What was reported |
|---|---|---|
| Test tube | Yes | AEDR bound tagged wheat histone proteins (2013) |
| Cells in a dish | Yes | Mouse embryo fibroblasts made two to five times more actin, tubulin and vimentin |
| Heart tissue in a dish | Yes | Rat heart tissue from young and old rats grew more; p53 fell (2009) |
| Live animals | Reported in a review | Threefold fewer deaths after induced heart attacks in rats |
| People | None found | No human study in PubMed, Europe PMC or ClinicalTrials.gov |
No human study of cardiogen or AEDR turned up in PubMed, Europe PMC or ClinicalTrials.gov. For heart research on other compounds, see peptides for heart and kidney health.

What Happened to Heart Tissue in a Dish
In the lab, cardiogen made heart tissue grow. A 2009 study grew heart muscle tissue from 3 month and 24 month old rats. Cardiogen strongly boosted cell growth in tissue from both ages. It also lowered the p53 protein.
Two more lab results add detail. In mouse embryo cells, AEDR raised the cell skeleton proteins actin, tubulin and vimentin by two to five times. In a 2013 test tube study, it bound to tagged wheat histones.
The 2022 review also puts AEDR on a list of molecules said to regulate inflammaging. That is the review's word for aging-linked inflammation in heart and vessel cells. The list also names liraglutide, covered in our liraglutide profile.

What the "Cardioprotector" Label Rests On
The cardioprotector label rests on rats and lab tissue, not on people. Here is each heart benefit and the kind of study behind it.
- Survival after a heart attack: rats only, reported in a review. Not tested in people.
- Less dead heart tissue: rats only, reported in the same review.
- Heart cell growth: rat heart tissue in a dish (2009 tissue culture study).
- Clogged arteries: not studied. No cardiogen study looked at artery plaque.
Because nothing has been tested in people, there is no human dose and no human safety record. The rat dose is not given here, since the original rat paper was not read.

Cardiogen Is Not CardioGen-82
CardioGen-82 has a similar name but is unrelated. It is a generator that makes rubidium Rb 82 injection. Doctors use it for PET scans of the heart muscle in adults with suspected or known coronary artery disease. If a search result shows an FDA label for "CardioGen", it is this scan product.
Common Questions
What is the peptide cardiogen used for?+
It is used in research, not as an approved treatment. Cardiogen is the tetrapeptide AEDR (Ala-Glu-Asp-Arg). A 2022 paper lists it as a cardioprotector. It has been tested on rat heart tissue, mouse cells and, as a review reports, rats after a heart attack. No human study was found.
Does cardiogen work?+
It has not been shown to work in people. A review by the group that developed it reports a threefold drop in deaths in rats given AEDR after a heart attack. A 2009 study found it boosted cell growth in rat heart tissue in a dish. No human trial was found.
What are the benefits of cardiogen peptides?+
Only lab and animal benefits are reported. In rats with induced heart attacks, a review reports fewer deaths, smaller zones of dead tissue and preserved glycogen in heart muscle. In cells, AEDR raised production of structural proteins two to five times. These have not been tested in people.
Is there a peptide that reduces clogged arteries?+
Not cardiogen, based on the research found. No cardiogen study looked at clogged arteries or artery plaque, and no human study of cardiogen exists in the records searched. The heart work on cardiogen is rat heart attack and tissue culture research.
Is cardiogen FDA approved?+
No FDA label for cardiogen was found. The only FDA label with a similar name is for CardioGen-82, a heart scan product that has nothing to do with the peptide.
Is cardiogen the same as CardioGen-82?+
No. CardioGen-82 is a rubidium Rb 82 generator, a radioactive product used for PET scans of the heart in adults with suspected or known coronary artery disease. It has nothing to do with the AEDR peptide.
