Alot of pro builders do use protein powder.Trust me, they are on my shipping log.I cant mention any names because they are endorsed by other companies.Just ask Dante from True Protein he will tell you.I bet you Dante like me ships to atleast a dozen or so pro athletes.Pro bodybuilders mostly use Whey Protein Isolate, and Waxey Maze Starch.Thats what I have the most requests for.The more advanced and intelligent ones will add Beta Casein, Egg Protein or Milk Isolates.
90% of the times its low carb Whey Protein Isolate they want.Most of them after training use Whey Protein Isolate with Waxey Maze Starch.
If you are a 200lb man and you want a awesome recovery blend.Take 30 grams of Whey Protein Isolate,60 grams of Waxey Maze Starch, 10 grams of L-Glutamine, 5 grams of BCAA's, and 2 grams of Beta Alanine.Then pop 3 grams of Vitamin C
This will give you excellent recovery, and cover give your body everything it needs to grow aswell as recover
