Engineered for
data you can trust.

Every batch passes a 6-stage QC protocol at our partner lab. From raw amino acid synthesis through HPLC, LC-MS, and microbial assay — they publish the data so yours has a foundation.

Solid-phase synthesis
Fmoc-protected Merrifield protocol on automated peptide synthesizers.
HPLC + LC-MS
Reverse-phase HPLC at 220nm and 280nm; mass confirmed to ±1 Da.
Microbial screening
USP <85> endotoxin + USP <61> bioburden assays per batch.
Cold chain logistics
−20°C lyophilized storage; insulated thermal shipping containers.
