<![CDATA[Finnrick vs Vendor COA’s]]>Browsing around the Finnrick site it struck me that in some cases there is a huge disparity between the purity stated on the vendor COA and the purity on the Finnrick COA. Anybody know what’s going on with that?

This batch (RET2412162025-12) was tested 6 times under Nexaph, lab E & G, ranging 24-27mg. The lowest was lab E again. (Krause)

Jano average was 27. Finn had a 27, 19, and one in between.

Beyond that i dont.

I then found a statement of correction for one vendor who protested. That correction was for that vendor only but it makes me question other tests due to the machine not being within calibration
