If Biotest protein shakes are anything like the normal whey protein shakes as far as decomposing over time, then no. Mix and drink. I dont recall reading much about it, but that would be my first guess. Someone can glad correctly me but I believe thats right.
- Eat more food and less protein shakes. You need to be eating fruits, vegetables, leans meats, etc and not concern yourself so much with the number of protein shakes. If you're eating more powder than solid food, there's something wrong. I drink one or two shakes a day, 40 g of protein each. Protein shakes ought to be a good addition to a healthy diet, not a replacement.
