Independent.
Verified. Trusted.
Quality Testing & Certificates of Analysis
Why Independent Testing Matters.
Every Peptidal compound is independently analysed by Janoshik laboratories - recognised globally as the gold standard for research peptide purity verification. Unlike many UK suppliers who rely solely on manufacturer claims, we send every batch for third-party purity testing before it reaches our customers.
What We Test For.
98%+ Purity Threshold
Every batch must exceed 98% purity before release. Any product failing to meet this standard is rejected and returned to the manufacturer.
Identity Verification
Mass spectrometry confirms each compound matches its declared molecular structure exactly.
Contamination Screening
All batches are tested for impurities, bacterial endotoxins, and degradation products.
Certificate of Analysis
A full COA accompanies every order, including batch number, test date, purity result, and laboratory verification stamp.
