Frequently Asked Questions

What is whey protein isolate?

Whey protein isolate (WPI) has the highest concentration of protein and BCAAs, while having less carbs, cholesterol, and fat compared to other whey proteins. WPI is also low in lactose and easy on the digestive tract.

What is HydroBeef?

HydroBeef is a premium, grass-fed beef protein isolate that’s hydrolyzed for fast absorption and easy digestion. It’s dairy free and naturally rich in collagen, helping to support healthy joints and connective tissues.

What are BCAAs?

Branched-chain amino acids (BCAAs) include leucine, isoleucine, and valine. They support muscle growth and reduce muscle fatigue.

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.
