- MGMike GMay 15, 20265.0Cameron is the man, guy deserves a raise! Very knowledgeable with all the products sold in the store, great customer service.
- CPchristine peraltaJun 14, 20241.0Tonight, I had my last scoop of pre workout.. no worries, or so I thought! I willI go to my local and (formerly) favorite GNC to restock, I arrived at 7:54 , plenty of time but the store was closed and the doors were locked. Even though it clearly states 8 pm closing time on the doors. 6 min left is a warm up and yet GNC decided to take away my pump, my energetic boost, the closest thing to appeal to the lifting gods all by closing 6 min early. What kind of world are we living in where a person can’t rely on hours of operation on a window on their local GNC to replenish their nectar from the heavens. I will take my millions elsewhere, perhaps the vitamin shoppe..
- YMY MuncherApr 3, 20242.0In line ready to pay but the inept clerk decided to assist a woman that came in after me! Her comment was?: "I was just trying to help her" when I said to her, "can I just pay" ? What happened to respecting those waiting in line? Very rude and unprofessional!²

- JRJm RMNov 11, 20175.0Great service very informative staff. They are honest and will tell you if something is legit or not.
