I ordered ten vials of a product, and 8 of them had the lyophilized powder shattered or chipped, indicating a possible issue in the lyophilization process. I contacted the company, and they assured me everything was fine. Now I have to pay for testing and potentially lose a vial to verify its quality. The company sells insurance but doesn’t support it. I usually purchase thousands of research peptides a month and wanted to make them my supplier, but I can't continue doing business with them when they refuse to honor their insurance policy. A simple search will show that broken pucks could signify a quality problem. Safety should come before profits.
