Science.bio Coupon Codes (No Longer Active) — Use This Instead
Last updated: May 2026.
Are Science.bio coupons still working?
No. Science.bio voluntarily shut down on January 27, 2026, citing regulatory compliance (source). Any “SCIENCE10”, “SCIBIO15”, “FREESHIP”, or other historical Science.bio codes you have in a password manager or saw on a coupon aggregator site cannot be redeemed because the storefront is offline.
The same applies to coupon listings on aggregator sites (RetailMeNot, Honey, CouponBirds, Knoji, etc.) — those listings have not been updated to reflect the closure. Treat any active-looking Science.bio coupon as stale.
Use this instead: WELCOME20 at Pure Chain Aminos
Pure Chain Aminos is offering displaced Science.bio customers a one-time first-order discount:
