I noticed a 2lb container of Twin Labs 100% whey protein powder in chocolate surge flavor at Kroger tonight for $14.99. I was wondering if anyone has any experience with this particular brand. I have only used GNC so far, but all small packages in local GNC stores have disappeared. There was also Body Fortress branded whey protein in chocolate flavor for same price. I was gonna get one of those, but thought I would ask here first. Opinions please! Thanks.
