Mass spectrometry (MS) confirmation: The observed molecular weight should match the theoretical molecular weight of the peptide within instrument tolerance (typically plus or minus 1 dalton for small peptides)
Over time, even under ideal conditions, peptide shelf life will reach its limit
Among the factors causing this rise are: Growing interest in natural beauty remedies, growing consumer demand for skin-brightening and anti-aging products, Transition to cruelty-free and clean-label products, and Growth of influencer-driven beauty marketing and e-commerce
