THE POWER OF SCIENCE FOR EFFECTIVE WEIGHT GAIN

MORE PROTEIN PER SERVING THAN OTHER WEIGHT GAINERS
This new and enhanced formula features a 67g multi-phase protein system (when mixed with 16 oz. of skim milk), which supplies fast-, medium- and slow-digesting proteins. The multi-phase protein system provides critical amino acids to the body at varying speeds for extended delivery of amino acids in the blood. The whey protein in Lab Series Mass Gainer Extreme XXXX has been filtered using Multi-Phase Filtration Technology for less fat, lactose and impurities.
MORE BCAAs AND L-LEUCINE PER SERVING
Lab Series Mass Gainer Extreme XXXX has been formulated with a massive 6.9g of L-leucine and 14.5g of BCAAs (when mixed with 16 oz.of skim milk), which help fuel your skeletal muscles, preserve muscle glycogen stores and help to reduce the amount of protein breakdown. These are some of the important nutrients athletes want to help increase muscle protein synthesis after a tough workout. Leucine itself is the key amino acid with the capacity to stimulate muscle protein synthesis. It does this by stimulating your body’s master protein synthesis regulator, mTOR.
