Is a purity figure from KP sufficient basis to skip independent testing?

Asked 8 Jul 2026Modified 22 days agoViewed 2.3k times

Stated plainly: purity figure · KP.

I would like to set this up properly once, rather than adjust it repeatedly.

My budget is real but not tight, and my tolerance for uncertainty is low.

What should I decide now, and what should I defer?

3I would gently push back on the second point — the evidence there is thinner than stated. – lyoph_cake 36 days ago

2Adding for future readers: the certificate should carry the lot number, not just a batch code. – w_okoye 9 months ago
