I purchases a protein supplement on today from GNC. The product is called Amplify Smoothie the worker said its pretty good. I'm pretty deficient in my protein I'm lucky to get in 20 grams a day. I'm right at 8 weeks post opt is this common? I can't eat very much without getting full. The protein shake powder cost me $ 60.00, before I break the seal do you guys think this was a wise investment for me?

I believe GNC has a satisfaction gaurantee. I was told by my GNC that if I did not like the product I could bring the unused portion back for a full refund. I would call and make sure and then try it if that is the case. You will have nothing to lose that way. Everybody has different taste so it may or may not work for you.
