This COA was tested by Janoshik, an independent third-party lab. However, the report is missing critical details including purity, quantity, endotoxin status, batch ID, and test date, making it impossible to assess the product's quality. The test recency is also unknown. While a verification URL is available, the lack of data severely limits its utility.
