Ever Vital is a US-based research compound supplier with third-party Certificates of Analysis, HPLC purity verification, and mass spectrometry identity confirmation documented for every batch. For researchers replacing Science.bio, which announced permanent closure on January 27, 2026, the catalog covers the same broad territory: longevity-focused research compounds, cognitive research peptides, and metabolic and healing research categories, all supplied strictly for laboratory research.
Why did Science.bio close?
Science.bio announced permanent closure on January 27, 2026 and, per The Peptide Catalog's roundup of the 2025-2026 vendor closures, committed to fulfilling all outstanding orders or providing full refunds before shutting down. The site today states it has permanently closed and discontinued the sale of research products, and warns that anyone claiming to be Science.bio or a successor is unauthorized and unaffiliated. Some community accounts describe a previous closure and relaunch, though the cited roundup covers only the 2026 closure; the current site does not reference that history.
Our full account of the closure is in Science.bio Shut Down: What Happened. For the sourced editorial timeline, Amino Axiom maintains a deep-dive at aminoaxiom.com/vendor-status/science-bio. Disclosure: Amino Axiom is part of the same brand network as Ever Vital, and this article recommends our own store.
What should researchers verify in a replacement supplier?
The closure wave of 2025-2026 rewrote the due-diligence baseline. Whichever supplier you evaluate, the checklist is the same:
- Batch-specific Certificate of Analysis. A COA tied to the production lot you receive, not a generic document reused across runs. Look for batch number, testing date, and the lab that ran the analysis.
- HPLC purity with the chromatogram. A purity percentage without the underlying chromatographic trace is a claim, not evidence. See Third-Party Peptide Testing: How to Verify a Vendor's Claims for how to check that the testing behind a document actually happened.
- Mass spectrometry identity data. Purity quantifies how much of the dominant species is present; mass spectrometry supports its identity by matching the observed mass against the theoretical value. A mass match alone cannot distinguish isomeric sequences built from the same amino acids, so where identity is critical, look for LC-MS data with tandem-MS (MS/MS) sequence-level confirmation.
- Net content versus purity. Two different numbers that are frequently conflated; our guide to net peptide content versus purity covers the distinction.
- Documentation you can keep. Retain COAs and batch records outside the vendor's account system. Several vendors that closed in 2025-2026 took their customers' order history offline with them.
