In 2004, CSBio opened a peptide production facility in Menlo Park, CA and in 2014, CSBio expanded production capability through the addition of a new, state of the art building dedicated to cGMP peptide production. In 2017, CSBio passed a FDA inspection and were recommended to be approved for commercial drug substance manufacturing. In 2023, additional cGMP clinical production capacity was added in Milpitas, CA.
