Axe's wife here. I need a yummy shake that is not sweetened with aspartame. Preferably something with very low carbs/fat and a whole mess of protien. I was using one scoop chocolate MetMax,but I get nasty headaches from the stuff. I like it because it really fills me up. I don't mind sweetening the shake myself. I can use stevia or cactus syrup ( I like this product alot. Does not spike blood sugar levels and has a nice taste with very small amounts.) Thanks for any responses.
