ARA-290 is a synthetic peptide studied for its selective activation of tissue-protective signaling pathways without engagement of erythropoietic activity. Research has investigated its role in inflammatory signaling modulation, microvascular communication, and neuro-immune interactions. Ongoing studies continue to explore its relevance in models examining nerve signaling, tissue stress responses, and immune-mediated pathways.
For research use only. Not approved for human consumption. Sold in lyophilized (powdered) form.
Our ARA-290 is synthesized to ≥ 99% purity, manufactured in the USA in GMP-compliant labs, and third-party tested for quality, consistency, and transparency.
