Some codes (typically those sent to specific customers via email) are restricted to a defined list of accounts. If you receive that message, the code wasn't issued to your account.

Every account gets a personal referral link. Share it with a friend, and when they buy through your link you earn a commission on their order. Your friend gets a small discount too. Sign in to your account dashboard to find your link and live referral stats.

Commission is profit-based — you earn a percentage of the margin on each qualifying order placed through your link. Exact rates are shown on your affiliate dashboard. Commission is calculated automatically as soon as the order is paid and shipped, and is held against your account balance ready to withdraw.

Your unique link is shown on your account dashboard. It looks something like rsbiolabs.com/r/YOURCODE — share it on social, in DMs, or via email. When someone clicks through, a referral cookie is set; if they then sign up or check out (as a guest or new account), the order is attributed to you for 30 days.

Once your referral balance reaches the minimum payout threshold (shown on your dashboard), you can request a payout from your account. Payouts are processed in GBP via bank transfer. Commission only becomes payable after the referred order has shipped and the 14-day refund window has elapsed.

No — self-referrals are not eligible. We monitor for duplicate accounts, matching addresses, or other signs of self-referral, and any orders found to be self-referred are voided and commission removed. Genuine referrals to friends, colleagues and your audience are absolutely encouraged.
