GNC is a store with great products and great value customer service. The staff is extremely knowledgeable and can talk to customers about proteins, vitamins, and the ingredients in all the supplies they sell. They are educated and can dictate what is in a customer's best interest regarding their workout regimen and the results they are looking for. During the week, customers meet friendly, nice people who take care of them and provide great interaction. The staff is personal and can multitask with other customers while having great conversations about health. However, on weekends, there can be other people who are not interested in the GNC business, which means they do not pay attention to customer needs. Many customers love the care they receive and highly recommend going here to anyone looking to surpass their limits or start a new journey, noting you will not get this kind of advice or product info from other retailers.
Mr. Paris is the most informative person I know on nutrition with great products the best store in Costa Mesa pull up GNC Harbor Boulevard and Baker Street.

I come to this GNC all the time and I really love it here. The guy who works there is super knowledgeable, always helpful, and makes great recommendations. The prices are good too, so it’s definitely my go-to spot for supplements.

Great experience. I had a lot of questions and Paris was super helpful and patient with all of them. Definitely coming back for the costumer service alone
