I have been having a very positive experience working with Watsonbio through several peptide synthesis orders with unusual amino acids. Watsonbio delivered good QC, quick turn around on orders, as well as very competitive prices.

Our first interaction with WatsonBio involved custom synthesis of some daunting peptide sequences that other synthesis companies had declined to attempt. WatsonBio accepted the challenge and successfully synthesized the peptides at a competitive price and with an excellent turnaround time. Since then, we have relied on WatsonBio to synthesize a variety of custom peptides ranging from simple to formidable, and they have consistently delivered high-quality peptide every time.
