At PES, quality always comes first and is the foundation of their brand. The industry contains numerous companies who scream top quality, but only few practice what they preach. Having proper quality control staff and procedures in place is an extremely expensive cost to a company, which is why so many avoid following true GMP (Good Manufacturing Practice). They take their research and development very seriously. Each product is carefully researched prior to release, developed into the best final formula, and geared towards giving the best results for our customers. The commitment they have given to research and development is one of the key reasons why they are known for their very active repeat customer base. They listen to customers, they hear each and every inquiry, and they know what the consumer wants as they are formulating.
