Short chains of amino acids made for scientific study. We supply them for in-vitro and laboratory research only; they are not medicines and are not for human or veterinary use.

Most compounds come as a lyophilized (freeze-dried) powder in a sealed vial. A few are also available as ready-to-use 30 ml solutions or in capsule form.

Every lot goes through six checks at accredited third-party laboratories: HPLC purity, mass-spec identity, endotoxin and heavy-metal screening, sterility, content quantification and a physical inspection.

Enter the lot number printed on the label in the COA lookup, or browse the purity reports.

Several compounds pre-measured into one vial for studies that look at them together. Each blend is verified to the same standard as a single peptide.

Keep sealed vials dry and away from light; many labs store them at −20 °C long term and 2–8 °C short term. Follow your institution's protocols once a vial is opened.
