Do You Just Whey?

If you're a regular whey protein user, there's something you need to know. When it comes to optimally building lean muscle, just whey protein is NOT ENOUGH. Nature had it right. When researchers tested a combination of whey protein + casein protein, as found naturally in milk protein, they discovered that the two protein sources work together in a synergistic manner to build lean muscle.

100% Whey protein in isolation only gets you so far... it can spike protein synthesis with an influx of amino acids, but quickly returns to baseline, leaving you where you started.

Enter casein, a slower-digesting protein that's typically consumed for its anti-catabolic properties as it promotes a steady release of amino acids over time.

In another published study, researchers found the combination of whey protein with casein protein resulted in a quick increase in protein synthesis along with a sustained elevation in plasma leucine levels. Plasma leucine levels are a key dictator of muscle protein synthesis, and thus, a combination of whey protein and casein protein may serve to maximize muscle protein accumulation.

This is the exact, real, validated science SELECT PROTEIN™ is formulated from...a combination of the highest quality Milk Protein Isolate and Whey Protein Concentrate 80%.

I'm very picky with protein shakes, this one was to sweet. I'll finish it, but won't buy again. Maybe chocolate would taste better.It does help with appetite better then other shakes but can't get past the taste.

Great profile, no dyes, overall great flavors (though snickerdoodle, arguably their most popular flavor, I just don't get snickdoodle from it, so is just ok for me as is Choc cupcake, just seems like plain milk chocolate to me) Best flavors, imo, Cake Pop and Frosted sugar cookie (and limited edition White chocolate macadamia) wish VS would at least carry these two.
