Frequently Asked Questions

What are peptides?

Peptides are short chains of amino acids that serve as building blocks of proteins. In research settings, peptides are studied for their potential roles in various biological processes and mechanisms.

Are your products for human consumption?

No. All products sold by BLL Peptides are strictly for in-vitro research and laboratory use only. They are not intended for human or animal consumption, and not for diagnostic or therapeutic purposes.

What is a Certificate of Analysis (COA)?

A Certificate of Analysis is a document that verifies the purity and identity of a product. Each of our peptides comes with a COA showing HPLC purity testing results, mass spectrometry data, and other quality metrics.

How should peptides be stored?

Most peptides should be stored in a cool, dry place away from light. Lyophilized (freeze-dried) peptides can typically be stored at -20°C for long-term stability. Once reconstituted, peptides should be stored at 4°C and used within a few weeks.

Do you offer free shipping?

Yes! We offer free shipping on all orders over $150 within the continental United States. International shipping rates vary by location.
