Good clean store. Helpful staff. I can chat for a bit or get in an out without hassle.

Solid staff, always polite. And will give you honest suggestions!

Wasnt sure what I needed. Andrew walked me through all the supplements and was extremely knowledgeable and seemed to really care about helping me meet my fitness goals. I usually buy a lot of stuff online but now Im gonna make all my purchases at GNC Marshalltown. Thank you Andrew.

They dont have everything. But its cheaper than online.

Always helpful.

Great products but high prices

Frank is AWESOME!! REALLY KNOWS WHAT HE IS TALKING ABOUT.

Google said it’s opened till 9 so I headed a town over got to the store right at 8 & the doors were locked.

Great deals !
