The products are good and the staff extremely honest and knowledgable, especially the manager. Very polite also. All products are satisfaction guaranteed or your money back. This is the only business I've ever known of that refunds opened products days or Weeks after purchase if customer isn't 100% satisfied. Seriously, I've had more success with things I've been taught and tried at GNC than I have had with most medical doctors, even specialists! The staff always seems happy to see customers and no one there has ever tried to sell me anything expensive, ineffective, or that I didn't need. They do their best to save customers money and their sales are HUGE! I love this GNC!
