Affiliate disclosure

Last updated: June 3, 2026

In line with the U.S. Federal Trade Commission’s guidance on endorsements (16 CFR Part 255), we want to be plain about how Alpha Index earns money.

We earn commissions on some links

Some outbound links to vendors are affiliate links. If you click one and make a purchase, we may earn a referral commission at no additional cost to you. Affiliate links carry a rel="sponsored nofollow" attribute and pass through a clearly labelled redirect page. Other outbound links are plain, non-commission links.

Our relationship with Alpha Pro Peptides

Alpha Index has a referral partnership with Alpha Pro Peptides and earns a commission (20% on a first order, 10% on repeat orders) on purchases made through our partner links. You should treat us as commercially connected to that vendor and weigh our coverage accordingly.

Money does not change the scores

Our scoring formula reads only four published, weighted axes (transparency, purity, shipping, value) and never reads any commission or partnership field. A vendor’s rank is computed the same way whether or not we earn from it. See our methodology for the full breakdown.
