What happened to Science.bio
Science.bio — a long-running research-compound supplier — shut down on January 27, 2026, one of at least eight significant vendors to exit in roughly nine months as enforcement tightened. Displaced researchers are now looking for a supplier with the transparency and reliability the grey market has lacked.
How to vet a replacement vendor in 2026
The 2026 enforcement wave (the FDA issued 50+ warning letters to peptide sellers in 2024–2025) means picking a replacement on price alone is risky. Use the buyer’s de-facto legitimacy checklist:
- Independent, batch-specific COAs — a Certificate of Analysis from a recognized third-party lab (e.g., Janoshik, with HPLC purity + mass-spec identity), matched to the exact lot — not a generic, reused document. This is the #1 trust signal.
- ≥ 99% HPLC purity — the industry benchmark for “excellent” (≥ 96% is the floor).
- A real physical address and card payments — crypto/Zelle-only is a red flag.
- US-based fulfillment — fewer customs seizures, faster delivery.
- Clear research-use-only framing — legitimate vendors never make human-use or medical claims.
