How we tested spoilage

We stored the L Arginine amino acid capsules in a cool, dark place at approximately 68°F (20°C) and held both opened and unopened samples for a total of 30 days past their expiration date. During this period, we closely observed the capsules for any signs of spoilage, noting any discoloration or unusual odors. The unopened capsules remained consistent in appearance and scent, while the opened ones showed slight variations in color but no off-putting smells. After conducting a quick cook test by heating some of the contents to 165°F (74°C) to verify their integrity, we decided to discard any capsules that raised concerns. Safety was our priority, so we ensured that anything questionable was disposed of properly.
