Use Representative Sample Sizes to Ensure Valid Stability Data

Understanding the Tip: Why sample size matters in stability testing: Stability studies aim to predict how a product performs over time under defined conditions. To derive meaningful conclusions, the number and selection of samples must reflect the variability of the batch and the product’s intended lifecycle. Too few samples may miss critical degradation trends; too…
