Which whey protein I should take? | Supplement Discussion | Forum

The difference between whey isolate and other protein powders is the small savings in calories, which is generally too small of a savings to make a difference in your diet. By consuming a protein shake immediately before training, another shake immediately after training would be redundant. The preworkout protein is capable of sustaining amino acid delivery into the post-exercise period. Besides, casein or a mix of whey and casein would be optimal following a workout. The whey provides a quick hit of aminos to boost protein synthesis while the casein provided a longer source of aminos to blunt protein breakdown. Net gains in muscle are the result of not just protein synthesis, but the inhibition of protein breakdown. Anyhow, I'm rambling. Getting the right amount of protein each day is the primary objective, and the rest is just nitpicking toward what might hypothetically clinch that extremely narrow edge.
