That's partly it. SPS is the protein already in the bloodstream so it's instantly recognized. It's like adding blood to your blood -- there's no conversion -- whatever you add, it's just more.
Also. the aminos in SPS are actually much larger than in food. (Including supplemental protein from why, egg, etc).
Yes, the new GEAR product will have SPS but it will also have whey FRACTIONS, which split the amino molecules. So now, you'll have the LARGER aminos from the SPS and they'll be DIVIDED into subparticals, creating a greater dispersion on nitrogen.
A simple concept, as is most good ideas and one I think it's pretty clever if I do say so myself.
