There are some sponsors on here that sell by the kilo. I'm not sure which one but it's real cheap.
The best local place I've seen is Sams Club.
They carry EAS whey 5lb for $27.
I really like the quality of EAS and it tastes great.
I have a brand new chocolate and vanilla and they are both yummy
Gosh damn I would like to see the 100lb bag ghost picked up.
I've tried the liquid just as an on-the-go thing - I would prefer food then whey or food and whey.
No whey ... "yes whey!" - couldn't resist
Cam if GNC is the cheapest you've found your not looking.
I order my protein from 5678 I think they are the cheapest.
I have gotten that stuff from sams...I thought it tasted ok...wasnt great...I do think its good protien for the money though...
