What ARA-290 is

Innate-repair peptide, plain

A small piece of EPO, with the blood-building part left out.

Studied for the repair signal, not the red-blood-cell one.

ARA-290 is a tiny piece of the hormone EPO, redesigned to keep one job and drop another.

(A peptide is just a short chain of the building blocks your body uses.) EPO is famous for telling the body to make red blood cells. ARA-290 is built from an 11-amino-acid stretch of it that taps a different switch entirely: a repair-and-calm-the-inflammation receptor, not the blood-building one.

It lives on the Healing + Recovery shelf near other repair-research compounds like BPC-157.

What it actually does

ARA-290 is studied for how it activates what researchers call the innate repair receptor, a signaling target involved in tissue protection and calming inflammation.

The interesting part is the split: it comes from EPO but does not push red-blood-cell production. So the research can look at the repair-signaling side on its own. That's the mechanism. We're describing what gets studied, not promising an outcome.

The research so far

ARA-290, also called cibinetide, shows up in inflammation and nerve-signaling research. You can dig into the literature on PubMed.

Repair receptor

Studied for the innate repair receptor, not the EPO blood receptor.

Inflammation signaling

How it relates to calming inflammatory signals.

Research only

We stock it for research. The studies write the conclusions, not us.

A precise way for researchers to study EPO's repair side in isolation.

The backstory

ARA-290 came out of work asking whether EPO's repair signal could be studied without its blood-building one.

  1. Carved out of EPO

    Built from an 11-amino-acid stretch of the EPO molecule.

  2. The blood part removed

    Designed to skip red-blood-cell production and tap the repair receptor only.

  3. Where it stands

    A defined receptor target in inflammation research. We're not telling you what it does for you, just the pathway studied.

What is ARA-290?
ARA-290 (cibinetide) is a synthetic peptide derived from EPO that targets the innate repair receptor without the blood-building effect, studied in inflammation research. Sold as a lyophilized powder for research use only.
What is the molecular weight of ARA-290?
ARA-290 has a molecular weight of 1208.28 g/mol and the molecular formula C50H81N17O19 (CAS 1208243-50-8).
How is the purity verified?
Every batch is tested by HPLC to at least 99% purity, and the Certificate of Analysis for that batch ships with the order and is shown on the product page.
How should it be stored?
Store the lyophilized powder cold and protected from light. Keep it sealed until use to maintain stability.
Does it come with a COA?
Yes. Every batch ships with its Certificate of Analysis, shown right on the product page, so you can confirm purity before you buy.
What does "research use only" mean?
It means this product is intended strictly for laboratory research. It is not for human or animal consumption, and nothing on this page is a medical or therapeutic claim.

Not for human consumption. Not approved by Health Canada. For in vitro research only.
