A peptide manufacturer built for buyers who need the same sequence, the same purity and the same paperwork on every reorder.
Synpepform began in a small laboratory in Xi'an's biomedical park, producing a handful of research peptides for local university groups. The work was unglamorous: couple, cleave, purify, lyophilize, test, repeat.
Twelve years later the same discipline runs a suite of solid-phase synthesisers, preparative HPLC columns and freeze-dryers, with more than 300 sequences in routine production. What has not changed is that every batch is released by our own QC team before it leaves the building - not by the supplier of the raw amino acids.
Filling line, fermentation suite, inspection bench and export stock — all on one site in Xi'an.
