What testing does and does not do. Laboratory testing on this page is analytical quality control for research materials. A test measures what is in the sample that was sent: its identity, purity, quantity, or a specific contaminant. A certificate of analysis covers only that sample, on that date. It does not establish that a material is safe or effective, it does not approve any product for human or veterinary use, and no product or material referenced here has been evaluated by the Food and Drug Administration. All materials are for in-vitro laboratory research purposes only. Not for human consumption.
Disclosure: Peptide Stores Online lists these laboratories for information and comparison. Most listings are plain links and earn nothing. Where a laboratory link is an affiliate link, it is marked as a partner link next to the link itself, and Peptide Stores Online may earn a commission on orders placed through it, at no extra cost to you. Affiliate status never affects whether a lab is listed or how listings are ordered.

Finnrick is a broker and rater, not a laboratory.
The performing partner lab does the analysis. Accreditation, if any, belongs to that lab, not to Finnrick.
Critics allege a conflict because graded vendors can pay monthly and launch fees, plus selection bias in crowdsourced samples and variance between partner labs. Finnrick's published position is that rankings cannot be bought and no payment alters ratings. Both positions are linked in the research report.
This is a plain link. Peptide Stores Online has no affiliate program with this lab and earns nothing from orders placed through it.
