Why COAs Matter
What a COA Verifies
A Certificate of Analysis verifies the identity and content of a particular compound, confirming the presence of the correct compound and that the labeled amount per unit is accurate.
Why Purity Can Be Misleading
Purity is most appropriate for neat peptide raw materials such as isolated or lyophilized powders.
For finished products like capsules or liquid sprays, a purity result can be misleading because it no longer represents the peptide alone in a simple system.
What Pure Bio Labs Reports for Finished Products
Identity of the Target Peptide
Chromatographic confirmation that the correct compound is present in your product.
Assay / Content
Meaningful confirmation that the labeled amount per capsule or spray amount is present, using methods validated for that specific formulation.
Scientific Accuracy Over Marketing Claims
Our goal is to provide COAs that are scientifically accurate, transparent, and not misleading.
