GNC Products??? & Recomendation of Protein shake for cut

[Monkey D Luffy]

Have any of use tried Any GNC products? People have told me that there stuff isnt that good. I have had some recomendations to get something called Zero Carb Iso Pure use herd of that? I have currently using Pro Elite 80 a gnc whey protien. It cost me 2kg for $80. And swanso if your reading this can you tell me what brand and wher you got that 5kg for $80 that you said you bought, i live in melbourne also so im wanting to not go over $150 for a 5-6kg tub if i can find something good. And im in cutting phase so something for that.
I was thinking of getting this GNC product but it had 4g of carbs is that too much when your on cutting diet?
I also been wanting to try order online such websites as www.supplements101.com but im scared that it might screw up or something lol anyone had experience with online protein buying ?
