Currently, before I lift I put in a 20oz Powerade with a scoop of whey. After lifting I will do the same along with some creatine or use a weight gain powder/whey shake combo.[/quote]
Try taking some BCAA’s (if you take them) and a SMALL amount of carbs (100-200 calories) example: 2 bananas, about 10-20 minutes before you work out. I use to have the same problem you described. It was from eating to much of the wrong thing before I worked out. That pre-lifting whey may be screwing you up.
IMO which may or may not be completely wrong, having a large amount of protein floating around in your system during a workout isn’t helpful or necessary. I understand that some helps prevent catabolism, hence why things like Surge help workouts a lot. The protein is mostly there to build muscle, and as its been said you don’t build your muscles while you lift.
