It has become overwhelming clear that intake of whey protein is crucial at two time points: Before and immediately after exercise.  This was first documented back in 2006 when researchers gave subjects whey protein either before/after exercise or in the morning and right before bed.  The group that received whey protein before/after exercise gained more muscle than the group receiving it at any other time. 

An exciting new study released this month in the Journal of Amino Acids reported that whey protein timing altered anabolic gene expression and enhanced muscle mass in men.  In the study, subjects were randomized to either receive a whey protein shake both immediately before and after exercise or a placebo (just carbohydrates).   The men performed resistance training for 21 weeks and had strength and muscle mass analyzed at the end of the study.  The group that consumed the protein before and after exercise had greater gains in muscle mass and strength compared to the placebo group.  Additionally, the whey protein before/after exercise group had an increase in satellite cell activity!  Don’t let you training suffer because of missing that key “anabolic window of opportunity”. 

Species ISOLYZE is 100% pure, cold-filtered, whey protein isolate. It’s the highest yield whey protein available on the market with an amazing 27 grams of protein per 29 gram serving size.
