No, it won't likely provide any increase on the protein synthetic response. IMO, pepto pro or whey hydro are actually superior to the mix I am using now but I bought so damn much I am stuck using it. Whey hydro and pepto pro have a decent percent of protein peptides, which are taken up faster than free form amino acids and they both have a high leucine content and any addition leucine, BCAA combo or full EAA blend won't provide a greater response than what you are getting now.
The only difference it would make IMO is if you extended your training period and hit more muscle groups whereby the additional amino acids combined with the complete proteins would be spread out over a longer period of time so each muscle group is getting sufficient amino acids for recovery once damaged through training.
That helps a lot. Thanks
