Research-grade peptides with a third-party Certificate of Analysis per batch
HI-tides supplies lyophilized research peptides from warehouses in California and Hawaii,
shipping to all 50 US states. Every compound is tested by an independent laboratory for
identity and purity before its lot goes live, and the resulting certificate is published on
the product page. All material is sold strictly for laboratory research use — not for human
or veterinary use.

packs. The reference article explains what the 0.9% benzyl alcohol preservative does, how it
is used to reconstitute a lyophilized vial, and why it is unsuitable for cell-culture work.
