Mick78 1 Posted September 5, 2010 Hello all, My wife recently discovered that if you buy any Protein powders at GNC and for some reason do not like them, you can either return them for exchange or get your full money back. I tried a few different ones, and the powder I liked the most is called muscle milk. Hopefully this helps someone. p.s. make sure and check with your local GNC I am not sure if this is a company policy. Share this post Link to post Share on other sites
