GNC aims to inspire people to live well. Whether someone is an athlete or just starting to focus on their health, we want to deliver the cutting-edge, efficacious ingredients and products they deserve.
If I could give GNC zero stars, I would. The products are overpriced junk that don’t work, and the customer service is beyond awful. But the real kicker? For the first time in my life, I walked into a store and genuinely felt like they didn’t even want my business for racial reasons. I’ve never had that feeling ever until today.
The staff acted dismissive from the moment I walked in, avoided helping me, and seemed annoyed that I was even there. No greeting, no assistance, just cold stares and bad attitudes. It was uncomfortable and unprofessional.
Pair that with their overpriced, ineffective products, and you’ve got the perfect recipe for a store I will never step foot in again. There are plenty of other places to buy supplements—places that actually want customers and treat them with respect.
the franchisor definitely needs to evaluate who handles there business as this is unacceptable.

My sister and I have been coming to this location for awhile now, part of it because we are huge snackers and this store has amazing options but also because of the staff (huge shoutout to Amanda) . Our experience(s) here are always positive and I can’t emphasize enough how much we adore this location and its team !!! :)
