Science.bio Shutdown 2026: What Happened & Where to Buy Now
Published: 2026-03-20Updated: 2026-03-26Category: Market Updates
Science.bio, one of the largest research chemical and nootropics vendors in the United States, ceased operations in early 2026. The website went offline, orders stopped processing, and no official communication was provided to customers. Here is the full timeline.
Timeline of the Science.bio Shutdown
| Date | Event |
|---|
| October 2021 | Science.bio discontinues SARMs product lines, citing regulatory pressure |
| 2022–2024 | Operations continue with reduced catalog focused on nootropics and reference materials |
| Late 2025 | Reports of delayed shipping, reduced customer support, intermittent website issues |
| January 2026 | Website goes offline. Orders stop processing. No official announcement. |
| February 2026 | Domain remains inactive. Community forums confirm closure. Unverified reports of inventory acquisition. |
| March 2026 | Website remains offline. Closure appears permanent. |
What Happened to Science.bio?
Unlike Peptide Sciences, which also ceased operations in 2026, Science.bio's closure was not preceded by an FDA warning letter or public enforcement action. The shutdown appears to have been a business decision rather than a regulatory seizure.
Several factors likely contributed. The 2024–2025 period saw unprecedented FDA enforcement — over 50 warning letters to GLP-1 compounders, expanded Category 2 listings, and ITC exclusion orders. Payment processing became increasingly difficult as mainstream processors flagged research chemical merchants. The market consolidated significantly, with smaller vendors unable to sustain operations.
Was Science.bio's Inventory Acquired?
Unverified reports suggest some inventory may have been acquired by another vendor. No acquiring company has publicly confirmed this. Researchers should exercise caution with any vendor claiming to sell "former Science.bio inventory" — there is no way to verify chain of custody, storage conditions, or purity without independent testing documentation.

Where to Buy After Science.bio
Researchers who relied on Science.bio need to evaluate remaining vendors carefully. The key criteria: third-party testing by an independent laboratory, published COAs downloadable before purchase, RUO compliance with no therapeutic claims, and US-based operations for faster shipping and clearer legal jurisdiction.

Science.bio Product Alternatives
Science.bio's catalog included nootropics and a limited selection of reference materials. For researchers specifically seeking verified alternatives with third-party COAs:
Pepta Labs carries
34+ research compounds at ≥99% HPLC purity with independent third-party testing.
Semax and
Selank — two nootropic compounds previously available at Science.bio — are in stock with published COAs. See our
vendor comparison for a side-by-side evaluation.
