Does an outside lab test every batch, and can you see the reports?
Reports name "Krause Analytical / Finnrick Analytics", which is not a recognized testing lab or is only partly identified.
What this means
An outside lab is a testing company the seller does not own. "Accredited" means an official body inspected the lab and certified its accuracy.

What this means

What this means
Whether you can see the lab reports before you buy, without making an account.

Results vs Our StandardWeak · 1.5 of 6 pts25of 100
Do the published results meet our fixed standard?
No purity results to check against our standard.

Too few reports list the measured amount to judge.
What this means
Our bar is within 10% of the label. A 10 mg vial should hold between 9 and 11 mg.
Independent Blind TestsNothing found · 0.0 of 14 pts0of 100
When someone bought it anonymously and had it tested, did it match the label?
No independent blind tests on record.
