Quality & Transparency
The COA Process
Understanding Certificate of Analysis (COA) standards — and how to tell rigorous testing from generic claims.
1
Why Are COAs Important?
A Certificate of Analysis (COA) is the document that verifies the identity, purity, and overall quality of a peptide. It’s the difference between a product that meets defined standards and guarantees integrity for laboratory research — and blind trust in an unverified claim. Every EvoLabs COA is built to be read, checked, and independently confirmed.

Premium vs. Generic Testing
Premium Methods
UV Absorption (HPLC + UV)
Chromatograms confirm purity and separate impurities clearly and accurately.
Mass Spectrometry (MS)
Verifies molecular-weight accuracy, reinforcing peptide identity and authenticity.
Generic Methods
Outdated or generic techniques that lack precision — producing inconsistent, misleading purity claims:
- Titration — basic concentration only, blind to impurities
- Infrared (IR) — detects bonds, insufficient for peptides
- TLC — basic ID, misses low-level impurities

How to Read & Interpret a COA
Testing MethodologyCOA explicitly lists HPLC, UV absorption, and Mass Spectrometry.
Purity PercentageA clear purity % with detailed chromatograms and impurity breakdown.
ChromatogramsVisual peaks labeled by retention time and purity percentage.
Identity ConfirmationMolecular weight checked against expected value via MS data.
Certifying AuthoritySignatures & dates from qualified analytical chemists.
Red Flags in a COA
- Absent or unclear analytical methods; missing chromatograms.
- Conflicting purity percentages across labs.
- Unsigned or undated certificates.
