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 your digestive tract.

What are BCAAs?

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

The days of loading your body with empty fat storing calories are over! Calories don’t stimulate muscle growth – anabolism does! High-speed macronutrient delivery with near-perfect insulin optimization sets CARNIVOR MASS apart from all others. Research shows that fast proteins combined with elevated insulin equals explosive muscle anabolism (growth) when combined with resistance training. CARNIVOR MASS makes this possible with MuscleMeds world famous CARNIVOR Beef Protein Isolate (BPI) acting in combination with iSpike, a dual insulin release/insulin signal amplifying technology not found in any other supplement. Beef Protein Isolate – Backed By Research To Build Muscle! Beef has proven itself as a favorite anabolic protein source for many athletes and champion bodybuilders. Clinical research shows that hard training male athletes supplementing with CARNIVOR BPI gained an average of 7.7 lbs. of muscle mass in just 8 weeks (a 6.4% average increase), while the placebo group only increased lean muscle body mass by 0.7 lbs. MuscleMeds hydrolyzed CARNIVOR Beef Protein Isolate (BPI) provides the power of beef at the speed of whey, delivering rapid absorption of high concentrations of amino acids without the lactose, allergies, fat, cholesterol and other problems associated with dairy products. This pure Beef Protein Isolate is also 350% more concentrated in amino acids than steak and more concentrated than whey. Plus BCAAs for even greater anabolic power! iSpike is an exclusive MuscleMeds technology designed to harness the full anabolic impact of insulin. Using fast-acting, reactive enhanced microparticulated carbs and insulin potentiators Chromium and D-pinitol (a cyclitol), iSpike causes a rapid elevation in insulin while simultaneously amplifying insulin signaling at the muscle receptors to potentiate maximum muscle growth, glycogen replenishment and tissue regeneration. iSpike works so fast and is so powerful, it helps stimulate anabolism within 30 minutes of your first delicious serving. This is the desired anabolic effect you want from your mass gainer and it can only be achieved with CARNIVOR MASS... the premium mass builder from MuscleMeds!
