Certificate of Analysis

Every Nexogen research formulation is intended to be released with a third-party Certificate of Analysis (COA) verifying identity, content and purity. The reports below are illustrative examples of the COA format — they are shown so researchers can see exactly what to expect. Batch-specific COAs for our in-house formulations are pending and will be published on this page as they are returned by the analytical laboratory.

Please note: the documents below are examples of what a COA would look like, provided for format reference only. They are not certificates issued against current Nexogen Research production batches. Verified, batch-matched COAs will replace these examples once analytical testing is complete.

RP-HPLC Purity

Reversed-phase HPLC at 214 nm is used to determine peptide purity as area-percent of the principal peak.

MALDI-MS Identity

Matrix-assisted laser desorption/ionization confirms molecular mass against the theoretical [M+H]+ value.

Independent Lab

All analyses are intended to be performed by an independent third-party laboratory under validated protocols.

Batch-specific Certificates of Analysis for Nexogen Research formulations will be published here as soon as third-party analytical testing is complete.
