Finnrick vs Vendor COA’s

[BillyS]

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?

I was looking today and found a batch of peptide tested from 19mg to 27mg. 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

@MyB I take their testing seriously when something comes back as not whats claimed in the bottle. Beyond that i dont.

@randy i found three tests for the same batch of R24 that I own. Jano average was 27. Finn had a 27, 19, and one in between.

@MyB did it say which lab was used for each test?

[MyB]

@randy this is the coa with the low reading, Lab E. https://www.finnrick.com/testing-certificate/retatrutide/ez-peptides/20260306-e-45yg2em
This batch (RET2412162025-12) was tested 6 times under Nexaph, lab E & G, ranging 24-27mg. The lowest was lab E again. (Krause)

@MyB that makes sense. we've seen a vendor use krause for a new shipment recently and they tested 20% under on a few things. shot the samples over to jano and AFI and it tested within 3% of the expected fill.
