Certificates of Analysis
Transparency is the foundation of trust. Every batch of peptides we supply is independently tested and documented.
Our Testing Process
All peptides stocked by BioLab Peptides undergo rigorous quality control before being made available for purchase. Each batch is independently tested by third-party laboratories using two gold-standard analytical methods:
HPLC (High-Performance Liquid Chromatography): Measures the purity of the peptide by separating and quantifying each component in the sample. Our minimum threshold is 99%+ purity.
Mass Spectrometry (MS): Confirms the molecular identity of the peptide by measuring its exact molecular weight, ensuring the compound matches its stated specification.
What’s Included in a CoA
Each Certificate of Analysis contains:
- Peptide name and batch/lot number
- Molecular formula and molecular weight
- Purity percentage (HPLC result)
- Mass spectrometry data confirming molecular identity
- Appearance and physical description
- Testing date and laboratory information
Requesting a Certificate
Certificates of Analysis are available for all products we sell. To request a CoA:
- Email us at support@biolabpeptides.co.uk
- Include the product name and your order number (if applicable)
- We’ll send the relevant CoA as a PDF within 24 hours
Why Purity Matters
Research outcomes depend on the quality of the compounds used. Impurities, degradation products, or incorrect molecular structures can compromise experimental results and waste valuable research time. By providing verified purity data, we help ensure your research starts on solid ground.
Our commitment: If any product is found to fall below our stated purity threshold, we will replace it or provide a full refund — no questions asked.
