Frequently asked questions

Do your peptides come with a Certificate of Analysis?

Yes. Every research peptide from BioBear includes a Certificate of Analysis (COA) from trusted, independent third-party laboratories. Each COA verifies purity, identity, and potency so you can proceed with full confidence in your research materials.

Store lyophilized peptides at −20°C for long-term stability, though 2–8°C is acceptable for short periods. Once reconstituted, solutions should be kept at 2–8°C and used promptly. Avoid repeated freeze-thaw cycles to preserve structural integrity.

Research compounds are materials supplied exclusively for scientific, analytical, and educational laboratory use. All BioBear products are labeled For Research Use Only and are not intended for human or animal consumption, medical use, or therapeutic application of any kind.

For Research Use Only means all BioBear products are supplied strictly for in vitro and in vivo laboratory research and scientific analysis. They are not approved for, nor intended for, human or animal consumption, veterinary use, diagnostic procedures, therapeutic applications, or any form of clinical use.

All BioBear products are verified at ≥99% purity through independent third-party testing using industry-standard methods including RP-HPLC and ESI-MS identity confirmation. Every product ships with a Certificate of Analysis confirming purity, identity, and potency — available directly on each product page.
