If you’re still using a whey protein shake around workouts then you haven’t been listening to my advice over the last few years and you’re actually undermining your results.
Just a few years ago we thought that whey was the absolute best protein source and only source to take before and after workouts. And it still is the best source of protein to take. It’s just not best to take it alone without other protein sources. There is a growing body of research that now confirms that combining the fast-digesting whey protein with at least the slow-digesting casein protein is better for muscle growth than just going with whey protein alone. Some evidence suggests that an even better strategy may be to provide a medium-digesting protein, such as soy or egg protein to that mix of whey and casein.buy now!
