Why COAs Matter
“Purity” is a term best suited for raw peptide materials like isolated or lyophilized powders, where a single compound is being measured against potential impurities.
For finished products such as capsules or liquid sprays, the formula includes additional ingredients like stabilizers and fillers. Because of this, “purity” can be misleading. Instead, the most accurate and meaningful way to test these products is by reporting:
- Identity of the target peptide
- Assay or content, confirming the labeled amount per capsule or spray
This approach reflects real analytical standards and ensures the data you’re seeing is both accurate and relevant.
All products are tested by an ISO 17025-accredited analytical laboratory to ensure consistency, transparency, and quality.
