Description
ARA‑290 (generic name cibinetide) is an 11‑amino‑acid peptide engineered from the helix‑B surface of erythropoietin (EPO). Unlike full‑length EPO, ARA‑290 is non‑erythropoietic (it does not raise red‑blood‑cell counts). It targets a tissue‑protective receptor called the EPOR–CD131 heteroreceptor (sometimes called the innate repair receptor), with the goal of reducing inflammation, protecting stressed tissue, and supporting small‑nerve fiber health. It is not FDA‑approved; products sold online are unregulated for identity and sterility.
