ARA-290 vs Epithalon

Non-hematopoietic EPO analogue; activates innate repair receptor (IRR/EPOR/CD131 complex) without erythropoietic effects; promotes tissue repair and nerve healing

A modified erythropoietin peptide that activates tissue repair pathways without stimulating red blood cell production. Strong evidence for neuropathic pain and sarcoidosis.

Epithalon is believed to activate telomerase, the enzyme responsible for maintaining telomere length, with several in vitro and animal studies reporting telomere elongation. It also appears to regulate the expression of p53 and other cell-cycle control genes, modulate the hypothalamic-pituitary axis via pineal gland activity, and upregulate antioxidant defences including superoxide dismutase and catalase.

Epithalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed from research into the pineal gland peptide complex epithalamin. It is researched for its role in regulating melatonin secretion, antioxidant enzyme activity, and telomere dynamics, with a body of work primarily from Russian research groups.
