I heard you should take a serving just within 30 minutes after your workout. Now my question, I usually work out and then do 40-60 minutes Cardio. so when should I take my protein? after the workout and before the cardio, or just after the whole thing, i.e. after workout+cardio?

I also heard that you can not lose weight and gain muscle at the same time, but I disagree, I managed to do that before, may be ur muscle gains wouldn't be as much as it would if you not losing fat, but there will be something.
