Disclose the relationship
An affiliate should clearly state that they may earn a commission when someone subscribes through their link or code. The disclosure must be close to the endorsement, easy to notice, and in the same language and medium.
Commercial transparency
Affiliate disclosure
Referral relationships support subscription growth. They do not shape evidence coverage, appraisal, or conclusions.

What it means
A material connection
Some links or promotion codes may identify a referring affiliate. If you subscribe through one, the affiliate may receive a commission from us on eligible collected subscription revenue. A discount applies only when the checkout page displays it.
The subscriber’s base price remains $10 per month unless checkout clearly shows a different promotional price, duration, next charge date, and renewal amount. Referral attribution does not create a clinical, employment, agency, or advisory relationship.
Standards for affiliates
Do not make medical claims
Affiliates may describe the subscription using approved factual materials. They may not claim that the service, a compound, or an entry diagnoses, treats, prevents, cures, prescribes, guarantees an outcome, or replaces professional judgment.
Do not imply editorial influence
Compensation never purchases coverage, ranking, evidence certainty, favorable conclusions, reviewer access, or an endorsement by The Evidence-Based Encyclopedia of Nootropics.
Respect subscriber privacy
Affiliates should receive only the attribution and payout information needed to administer the program. They should not receive subscriber reading history, payment credentials, or health information.
Promotion guardrails
Clear at checkout
- The discount value, duration, eligibility, and future charge must be displayed before subscription consent.
- A $0 transaction does not earn a commission and has no payment to refund.
- Refunds, disputes, and chargebacks may reverse related affiliate credit.
- Self-referrals, deceptive domains, impersonation, spam, hidden redirects, and coupon leakage may be prohibited by the final program terms.
Suggested plain-language disclosure
“Affiliate disclosure: I may earn a commission if you subscribe using this link or code.”
A personalized code alone may not clearly communicate the paid relationship. Affiliates remain responsible for making a conspicuous disclosure wherever they promote the service.
