I don't always go to GNC or any nutrition store for that matter but lent and training had me wasting away. Since muscle atrophy isn't my goal, I had to make an emergency stop here while I was in the area.
The girls that worked the day I came in were helpful. They were honest about the products and didn't try to sell me other things I didn't want/need. My friend warned me about his experience about people trying to sell him supplements he didn't need.
They offer a gold card you can use for discounts/benefits that expire a year later. It's $15 for the card but it saved me $60 so it paid for itself.
They have blender bottles, water bottles, protein shakes, protein powder, pills, chews, liquids for all your nutrition/supplement needs. They have free samples of certain items so you can test it before you commit.
