CERTIFICATE OF ANALYSIS

PT-141 10mg

39747

Supplier certificate

Content came back at 9.177 mg against a 10 mg label, which is 8.2% under. The certificate records that as conforming but does not print the tolerance it is conforming to. ClearBatch states a fill window of 15% either way, and this sits inside it. The figure above is exactly as the laboratory reported it. Chromate access code BATCH1QTFWM2.

Supplier certificate, lot matched. Chromate tested this sample for ClearBatch, the supplier who manufactured the material we resell, so it was not commissioned by Sentient Biogenix. But the batch code on it, CBQB-2608-PT141-10, is the code printed on the tray our own vials came in. The laboratory is not ours. The lot is.
