There are several things that add considerable cost to all cGMP manufactured peptide products . Among those are the requirements for QA review, process validation, stability studies, and recurring personnel cGMP training. In some cases, products that meet multiple compendial monographs may require more than 20 to 30 individual tests consuming days or even weeks of a technician’s time. cGMP products often require special packaging precautions such as tamper-evident seals, as well. All of this additional testing, time and document preparation and review significantly is not required for non-GMP grade peptides.
