Incorrect. Hydrolysate and hydrolyzed are two different things.
....The main competitor for the title of best protein is whey isolate, but after reading the following you'll see that it comes in a distant second to hydrolysate. Although you wouldn't have to worry about a catabolic decline in blood aminos with whey isolate, it has its own problems.
Even though it used to be considered very high quality, whey isolate takes more than two full hours to elevate blood amino acid levels so that they reach desired levels (Dangin et al., 2002). Having an absorption time one third longer than hydrolysate, whey isolate will give a smaller peak in amino acid levels and reduced protein synthesis stimulation as shown in Figure 2. In other words, we can have a peak twice as high or one that lasts twice as long for a given quantity of protein ingestion, but we can't have it both ways.
