AI summary Trust: low Third-party lab

Janoshik tested this MK-677 sample, but the COA does not provide a purity percentage or chromatographic data. It shows four distinct quantity measurements (23.07 mg, 22.09 mg, 23.47 mg, 21.79 mg), suggesting replicate analyses or inconsistent sample composition. The test is stale (over a year old), and no endotoxin information is available. Customers can cross-check on the lab's public verification URL.
