Inside the lab
Our chemists run solid-phase synthesis, reverse-phase purification, and analytical release in the same facility. Researchers get one point of contact from the chromatogram to the vial in their freezer.


Quality control
Every batch is assayed by reverse-phase HPLC and released only above 98% purity.
>98% purityMolecular weight confirmation ensures sequence identity before lot release.
MW confirmedVials ship on gel packs in insulated mailers within 24 hours of order.
