Cells either received 200 M TBHP alone or co-incubation with NAC, NACET, or diNAC at a range of concentrations, where 200 M had been previously demonstrated to be the maximum concentration to not significantly affect cell viability in ARPE-19 cells [25]

Analytical Verification Every batch undergoes Mile High Compounds comprehensive analytical protocol: High-Performance Liquid Chromatography (HPLC) for purity quantification of each component Mass Spectrometry (MS) for molecular weight and identity confirmation of all four peptides 14-day sterility testing Endotoxin analysis 4-vial batch conformity verification statistically robust consistency testing across each production batch, exceeding the industry-standard single-vial sampling approach Heavy metal screening for lead, arsenic, cadmium, mercury, and additional trace metals Container and seal integrity verification Batch-specific Certificates of Analysis (COAs) accompany every order, documenting full testing results for all four component peptides
