Science.bio Coupon Code 2026 — SBREFUGEE25 (20% Off Pure U.S. Peptide)
Science.bio announced its permanent closure on January 27, 2026. To welcome former Science.bio researchers, Pure US Peptide is offering 20% off your first order with the code below.
Why we're running this code
On January 27, 2026, Science.bio announced its permanent closure to customers via Facebook (post 951466978871034) and email. The longevity, nootropic, and biohacking research community lost a familiar U.S.-based supplier. SBREFUGEE25 offsets the friction of switching vendors and re-validating supply against your prior Science.bio purity baseline.
For the full closure timeline and primary sources, see our companion explainer: What Happened to Science.bio. For a side-by-side comparison and our 32-compound research catalog, see the Science.bio alternative page.

Frequently asked about the coupon
Is SBREFUGEE25 stackable with other discounts? No — the code is a standalone first-order discount and does not stack with bundle pricing or sitewide promos. Pick whichever discount yields the larger reduction at checkout.
Does it expire? The code is currently active for the post-Science.bio wind-down window. We will keep it live as long as former Science.bio researchers are actively migrating; check this page for the current status.
Do I need to prove I was a Science.bio customer? No proof is required. The code is open to any new researcher placing a first order at Pure US Peptide.
Will it work on bundles or stacks? The code applies to the cart subtotal including bundle and stack products. If you are validating a first-batch order across multiple compounds, a stack often gives the best per-mg cost basis.
