International Protein Synergy was designed as a specific muscle growth (anabolic) protein. The proprietary blend of 6 proteins provides hard-training athletes with a superior natural amino acid profile essential for muscle growth. Hydrolysed Whey Protein Isolate (Whey Peptides), High Glycomacropeptide Whey Protein Isolate (WPI), Whey Protein Concentrate (WPC), Calcium Caseinate, Egg Albumen, and Milk Protein Isolate were carefully selected not only for their specific amino acid profiles, but for their unique absorption rates. As a result, Protein Synergy delivers a constant supply of essential amino acids into the bloodstream for hours, helping maintain a high positive nitrogen balance for maximal muscle growth.
Almost immediately, Protein Synergy starts providing your body with di- and tri-peptides from hydrolysed whey protein isolate — the most rapidly absorbed protein available. These peptides initiate the muscle-building process by stimulating the liver to produce anabolic growth factors that support muscle development. WPI and then WPC continue the supply of amino acids and whey fractions to the body. WPC also delivers the amino acids needed to produce higher levels of glutathione within the body. Glutathione is a powerful antioxidant that boosts immune function and protects the body from oxidative exercise stress, which can otherwise slow progress and reduce muscle gains.
Being more slowly digested than whey but faster than casein, egg white albumen sustains the delivery of muscle-building amino acids, while casein begins its slow release for up to 7 hours. Casein’s extended digestion not only prolongs the body’s positive nitrogen balance but also enhances the absorption of its amino acids — including muscle-sparing glutamine, threonine, and arginine.
One of Protein Synergy’s key strengths is how easy it is to drink. Great nutritional benefits mean little if the product isn’t enjoyable to consume. That’s why its delicious flavours and smooth, full-bodied consistency have been carefully developed to ensure each shake leaves you satisfied but not bloated.
