Launch with Finnrick
Some of the samples listed on this page were submitted by their vendor, as part of the Launch with Finnrick vendor support program.
The program is designed to help vendors get listed on the Finnrick web site while protecting the integrity of our rating system.
The vendor submitted four samples per product, two of which were tested by Finnrick for identity, purity and quantity according to our usual process. The vials were anonymized before being sent to the testing lab.
