Before you decide to pick a packing solution for your product, you may want to read some of the online reviews for GSC and see how they treat their employees and the care given to the products. Ask Robert Shapiro for a list of the qualifications in food safety, current certifications for himself and his staff, audit results (both internal and external), and current contracts pending before making a final decision. GSC is not a member of the BBB, the management has hidden salmonella findings from the Department of Agriculture as early as 2012. They have lost most of their management staff within the last four months (most resigning in fear of being tied to lawsuits or poor treatment) and the ones remaining have little or no food training. Even on their site, they list that pharmaceutical standards are being used, but the food service has a completely different set of standards which shows the lack of knowledge from the top down. Ask yourself "Why would a company use diabetic testing material standards on protein powder equipment or products?" Simply do a search for GSC packaging and read more about their employee working environment, termination of close to 80% of their staff just days before the 2012 holiday season, ask to speak with past contracts, and ask to walk through both the storage facility and production facility before you decide. You could be doing yourself the biggest favor just by simply talking to their floor manager to get an idea of who will be in charge.
