How to Read a ARA 290 Certificate of Analysis (COA)
A Certificate of Analysis is only useful if you know which number on it matters for the compound in front of you. For ARA 290, the informative checks are not the same as for a generic short peptide.
Overview
Check the weight matches about 1257 and that the purity trace is clean.
What ARA 290 actually is
A short 11-part peptide modelled on the repair-signalling corner of EPO, built to switch on tissue repair without EPO's effect on red blood cells. It is studied around nerve comfort, inflammation, and healing.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Assays that are informative for ARA 290
What to check on the COA
Confirm the observed mass matches the ~1257 Da target for the free peptide, and check whether peptide content is reported separately from chromatographic purity.
Deletion sequences from incomplete coupling; deamidated related substances eluting close to the main peak.
Verify a Popular Peptides batch
Every batch is third-party tested by HPLC and LC-MS with a published Certificate of Analysis (≥99% purity). Enter a lot number to pull the COA for the exact vial in front of you.
What ARA 290 is studied for
Studied for selective engagement of the EPOR/beta-common receptor heteromer that mediates tissue-protective signalling, distinct from the classical erythropoietic receptor.
A substantial share of the published literature examines small-fibre and neuropathic-pain research models.
Investigated for modulation of inflammatory pathways in preclinical tissue-injury models.
