Does QYB issue lot-specific documentation, or a batch certificate?

Asked 7 May 2025Modified 15 months agoViewed 3.1k times

I have both a purity figure and a content figure, which is why the discrepancy is visible.

I have the document in front of me and I can read the numbers. What I cannot do is interpret them.

I am reasonably comfortable with statistics and completely uncomfortable with chromatography, or vice versa.

What is the correct interpretation, and what is the common misreading?
