When building lean muscle, 100% Whey is INFERIOR

If you’re a regular 100% whey protein user, read on, because there’s something you need to know. Our investigation into the science should royally piss you off. I sure was…

In our quest to build muscle, protein intake is the single most important factor. When I say intake, I don't just mean amount...I mean the type of protein too.

Reputable journals have already tested the effects of different proteins in human subjects, and the data could not be more conclusive. Whey + Casein is the superior choice.

The media tells me that whey builds muscle. And you know what? They're totally right. Studies do show that whey alone builds muscle better than other proteins. But if you look what they compare it to, the issue is clear: studies compare whey to weak products like soy-based protein, sugary drinks, and even just water. Of course whey is going to come out on top!

Nature Had It Right

When researchers at a world-renowned clinic tested a combination of whey + casein protein, as found naturally in milk protein, they discovered that the two protein sources work together 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. Casein actually results in more retention of ingested protein than whey!

Whey protein hits the bloodstream at a fast rate, but it is casein protein that has been shown to create the strongest leucine balance. It only makes sense to consume them together.

Studies have repeatedly shown that milk may be the optimal post workout drink due to the unique delivery and interplay of milk protein's components: whey protein and casein protein, together. Nature had it right all along: milk protein is king.
