How this directory works
Facts on file, not decoration
Badges like third-party tested, Janoshik verified and COA available appear only when the corresponding record exists in our database. If a vendor has no verification data, we say so.
Two rating signals
Listings carry an editorial rating and a separate community average from approved user reviews. Directory ordering is featured placement first, then average rating.
Affiliate disclosure
Some outbound links are referral links that may earn us a commission at no extra cost to you. They are marked as sponsored and do not change what we record about a vendor.
Keep researching
Research use only. All vendors are listed for laboratory research purposes. Nothing on this page is medical advice, and listed compounds are not for human consumption.
