Stability Testing

Stability testing is a regulatory and quality assurance process that evaluates how the quality attributes of a pharmaceutical or research product change over time under defined environmental conditions, including temperature, humidity, and light exposure. For peptides, stability studies monitor parameters such as chemical purity (degradation products), physical appearance, pH, sterility, and biological potency at specified time intervals. ICH guidelines define three standard conditions: long-term (25 degrees Celsius, 60% RH), intermediate (30 degrees Celsius, 65% RH), and accelerated (40 degrees Celsius, 75% RH). Peptides are inherently susceptible to degradation through hydrolysis, oxidation, deamidation, aggregation, and disulfide scrambling, making stability data essential for determining shelf life and storage requirements. ORYN peptide pens are formulated with optimised buffer systems and stored under cold-chain conditions to maximise stability. Real-time and accelerated stability data inform the expiration dates printed on each product and validate that the precision pen delivery system maintains peptide integrity throughout its intended use period.
