Quality documentation

Certificates of Analysis

Each certificate is issued by an independent laboratory and confirms a compound’s identity and purity. Certificates are published here as each batch is verified.

Reading a certificate

01

Identity

Mass spectrometry confirms the molecule matches its expected molecular weight — the vial contains what the label states.

02

Purity

High-performance liquid chromatography (HPLC) measures what percentage of the sample is the target compound.

03

Batch

Each certificate refers to a specific production lot, so its results apply to vials from that batch.

04

Independence

Testing is performed by a third-party laboratory, not by Arete Biolabs.
