Affiliate & Advertising Disclosure
This page discusses GLPro without linking to its seller, and separately recommends an Amazon product as an alternative. Here's exactly how each relationship works.
Last updated September 2026
GLPro: no paid relationship
We do not have an affiliate, advertising, or any other paid relationship with GLPro's seller (tryglpro.com) or with any of the additional similarly-named websites we identified during research. We earn nothing if you buy GLPro from any of them, and this page does not link to any of them.
The Amazon link: a disclosed affiliate relationship
The single product link on our product page — a standalone berberine supplement, offered as a more transparent alternative — is an Amazon Associates affiliate link. If you click it and buy something on Amazon, we may earn a commission, at no additional cost to you. This is how this page is funded; we don't run other advertising or charge visitors anything.
How we chose that alternative
We picked a single-ingredient product, at a disclosed standard research dose, that relates directly to the ingredient most consistently associated with this product's category across the secondary sources we found. We don't independently test products ourselves, and — as our product page explains — we can't confirm GLPro's own capsule actually contains this ingredient, since GLPro's own seller page names no ingredients at all. The ingredient and dosage information we cite comes from the cited sources' own publications.
