Peptides are short chains of amino acids that serve as building blocks of proteins. In research settings, peptides are studied for their roles in tissue healing, metabolic regulation, and cellular signaling.

Are your products for human consumption?

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

What is a Certificate of Analysis (COA)?

A COA verifies purity and identity. Every BLL Peptides batch includes HPLC and mass spectrometry results confirming 98%+ purity.

Where are BLL Peptides products manufactured?

All products are 100% USA-manufactured in GMP-certified facilities with independent third-party testing on every batch.

Do you offer free shipping?

Yes — free shipping on all orders over $150 within the continental United States. Orders ship Monday through Friday.

How should peptides be stored?

Lyophilized peptides should be stored at -20°C for long-term stability. Once reconstituted, store at 4°C and use within a few weeks.
