“Despite containing 5 consecutive arginines, the 15mer peptide was delivered with >90% purity. MS/MS data confirmed sequence accuracy. Impressed by the handling of difficult residues.”
DIANA MOORE
Designer
“Ordered 10 mg-scale of a tumor-targeting peptide for preclinical trials. All vials passed endotoxin testing and showed batch-to-batch consistency. Trustworthy for large projects.”
JESSICA KYLE
Manager
“Emergency 8mer with acetylated N-terminus arrived in 7 days with >97% purity. Saved our cell migration assay timeline. Excellent rush service for time-sensitive research.”

“Lyophilized peptides in pre-weighed aliquots with mass spec reports eliminated our QC workload. Perfect for high-throughput screening. Will adopt this as our standard procurement.”
LIAM BOWER
Mechanic
“Received detailed solubility recommendations for our hydrophobic sequence. The pre-shipment QC report included RP-HPLC, MS, and amino acid analysis—exceeding standard industry practices.”
