MM Carnivor is a decent whey substitute if you're fond of fruit flavored proteins, but there are so many choices in that price range that have excellent profiles. Ultimately your protein supplement is not going to be anywhere as significant as your whole food diet so take protein shakes with a grain of salt. That being said, if you're buying Syntha on a regular basis, you'd most likely be better off using a highly rated whey like iForce Nutrition's, which has been reviewed and almost universally loved by many members of AM, or . Their profiles, flavors, and consistency are tough to beat.
Remember...whey is a supplement. Eat real food, don't sweat your supplementary choices so much.
