Independent testing can provide an additional layer of confidence when evaluating research materials.
One of our returning customers independently submitted Tirzepatide samples for third-party laboratory testing on three separate occasions. The reported purity results were:



99.66%
99.92%
99.86%
In the May test, the third-party Certificate of Analysis identified the sample as Tirzepatide 30mg, confirmed its identity by LC-MS, and reported 99.92% purity by HPLC-UV.


After receiving the latest test result of 99.86%, the customer shared positive feedback with us:
“I had a 3rd party COA come back at 99.86% pure… I really appreciate it. I am getting my next order together and will definitely be reaching out to you soon.”
What matters to us is not a single test result, but the consistency demonstrated across multiple independently tested samples.
We support customers who choose to conduct their own third-party verification and can provide available batch documentation and COA information for reference.
