Testimonials
GenScript peptide synthesis gives us amazingly fast turnaround time and very competitive prices. Their peptide quality has been excellent. Our experience with them has been so positive that we have essentially shut down our internal peptide synthesis efforts and now use them for all of our custom peptides.
