I would like to know how sure we can be that it is indeed the proper molecule, if we have the lab result with MS and HPLC data. I feel that there are a lot of nuances there, and there are ways to make these tests pass, but still have a different molecule, and isomer, same amino acids but wrong sequence, etc. HPLC relies on the reference samples and calibrations, but how good those reference samples are, how often the calibration is done, etc. An discussion with a knowledgeable lab person would be nice.
