How we make money
Some links on this site are affiliate links: if you buy through them, we earn a commission at no extra cost to you. That is how the site is paid for. These are the rules that keep it from touching the evidence.
Who we earn from
Right now our only affiliate partner is Qualia (Neurohacker Collective), through the Refersion network. If that changes, this page changes first.
Every Qualia product we link to, with its dated price and our grades for its ingredients, is on the Qualia products page. A small Try nootropics button opens the same list, and after you have read a few pages the list may open once on its own; closing it keeps it closed for 14 days.
Rules we follow
- Grades and claim verdicts are commercially blind. Grade and claim records cannot reference affiliate data.
- Our partner is graded on the same rubric as everyone else: its products and the claims made for them are checked against the same evidence, and published when the review is approved.
- Guides that mention products include the best-evidenced option whether or not we earn from it.
- We say we earn a commission, in plain words, above the first affiliate link on every page that has one.
- Commercial modules sit in a labeled, dashed box so they never look like evidence.
How affiliate links work
Affiliate links go through a short address on this site that starts with /go/. It records the click and sends you to the shop. These links are marked as sponsored for search engines and are never indexed.
Discount codes
The deals page lists only codes we have tested at checkout, with the date we last checked them. Expired codes come off automatically.
