PRO7EIN Synthesis™ GAINER is also enriched with BCAAs, N-Acetyl-L-Glutamine and all the Essential Amino Acids designed to aid in muscle recovery and prevent the breakdown of lean muscle. In addition, Colostrum has been added to this unmatched formula to assist in the building of lean muscle. Colostrum contains insulin-like growth factor-1 (IGF-1) which is critical for stimulating muscle growth and immunoglobulins, which are involved in immune functions. THE ADDITION OF AMINOGEN®: Aminogen,® a vital ingredient in high-quality protein supplements, is clinically proven (Journal of The International Society of Sports Nutrition) to increase the BCAAs from your protein by over 250%, raise your Amino Acid levels by over 100% and boost your Nitrogen Retention levels by an incredible 32% to dramatically stimulate protein synthesis and muscle growth. Aminogen® is a patented, Bio-Active Enzyme System which breaks down protein and greatly improves amino acid absorption which equates to greater results. A natural, plant-derived enzyme, Aminogen® is ideal for increasing lean body mass and strength and promoting deep muscle recovery. Bottom line: When it comes to digestive enzymes in a protein product, Aminogen® ranks at the top of the list. FACT: Consuming protein-based weight gain supplements alone WILL NOT trigger explosive muscle gains. It is how well your body absorbs protein that will determine whether you get the results that your muscles are starving for. Get more out of your protein with Aminogen.®!
