Affiliate disclosure

As an Amazon Associate I earn from qualifying purchases.

Tested by John is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.

What that means for you, in line with the FTC's Endorsement Guides:

• The "Check it on Amazon" buttons and the storefront links on this site are affiliate links. If you buy through one, I may earn a small commission.
• It costs you nothing extra. The price on Amazon is the same either way.
• The commission doesn't change what I say. I show what works and what doesn't, and the honest notes stay in the videos.
• I don't show prices or ratings here. Check the current details on Amazon before you buy.

Health-related products (like pet supplements or foot supports) are reviewed for what they are and how they fit into my routine. Nothing on this site is medical or veterinary advice.
