Product Overview
ARA-290 (cibinetide) is an 11-amino-acid peptide derived from the helix-B region of erythropoietin (EPO). It was designed to activate the tissue-protective "innate repair receptor" without stimulating red-blood-cell production, separating EPO's cytoprotective effects from its hematopoietic ones.

Product & documentation questions
How do I read the size and pack quantity?
The per-vial size and number of vials per pack are listed separately in the table. The displayed price is for one pack. A blend’s stated size can describe combined ingredients; check its product label and report for individual components.
How do I find the matching COA?
Match the product, SKU and batch number with the published report. Open the batch page to read the actual results, original report and laboratory verification link. Ask support to confirm the allocated batch if it is not on your order.
Does a purity result mean every test passed?
No. Identity, purity, fill and endotoxin are separate measurements. Read each reported result and unit. An absent result is not a pass, and a less-than result is not zero.
Research Information
ARA-290 is used to study tissue-protective and anti-inflammatory signaling through the innate repair receptor (a complex of the EPO receptor and the β-common receptor). Research focuses on neuropathic, inflammatory and metabolic-stress models where erythropoietic activity would be an unwanted confound. Supplied strictly for in-vitro and laboratory research use only — not for human or animal consumption.
