About the labGenuinely independent

A unique code on every certificate, checkable by anyone at any time, so a result can never be faked or recycled.
Full chain of custody
Each sample is logged, sealed and tracked from the moment it arrives until it is disposed of. Nothing is assumed.

Notes on testing, methods and what we find.
What people ask about Attesta Labs.
What is a certificate of analysis?
A certificate of analysis, or COA, is a document issued by an analytical laboratory describing a specific sample as received and tested. It states the methods used, the parameters measured, the specifications applied and the results obtained. An Attesta certificate also carries a unique code so anyone can confirm it is genuine.
How do I verify an Attesta Labs certificate?
Enter the unique code from the certificate at attestalabs.com/verify. No account or sign-up is required. If the code is on the laboratory register, the full result is displayed; if not, the certificate is reported as invalid.
What does independent testing mean at Attesta Labs?
Attesta Labs sells nothing it tests and tests nothing it sells. The laboratory has no brand partnerships and no commercial interest in any outcome other than the accuracy of the measurement. Failing results are reported exactly as found.
How long does analysis take?
Standard turnaround is three to five working days for most services. Identity confirmation and purity/potency can complete in two to four working days. An optional Express 48 priority service is available where the laboratory schedule allows.
What standards do Attesta methods follow?
Methods are developed and validated in line with ISO/IEC 17025, USP <621>, Ph. Eur. 2.2.46 and FDA 21 CFR Part 211. Each method is validated for specificity, accuracy, precision and detection limits before it is used to report a result.
