Umm just from the abstract: " CONCLUSION: The ingestion of whey protein immediately before the start of exercise and again after each training set has no effect on muscle mass and strength in untrained young adults. "
there is a big AND in there I suggest using more relevant studies next time

"The researchers concluded that muscle metabolism after exercise can be manipulated via dietary means. In terms of the most beneficial timing of protein intake, immediate postexercise consumption appears to be best. Furthermore, leucine may play an especially important role in stimulating muscle growth in the postactivity recovery period."
And I am aware of mixed macros, the point was where the amino acids are coming from, not what is ingested with them
