Gaspari nutrition took sports nutrition to the highest level with the original sizeon?, the original intra-workout creatine drink. There wasn’t any doubt it represented a serious innovative leap forward in the creatine category. The original sizeon formula clearly demonstrated its effectiveness in a clinical setting and quickly became known as the king of creatines. As clinical research advances, so does gaspari nutrition which is why sizeon has now evolved into the ultimate hybrid intra-workout whey hydrolysate creatine formula. Once again gaspari nutrition raises the bar even higher in the sports nutrition industry!your body requires that proteins from whole food, whey isolate, casein, etc., be broken down in a process called “hydrolyzation”. This is an integral process which allows di and tripeptides to be absorbed and utilized for numerous processes including muscle building and repair. The problem is that while your muscles are starving for these nutrients (i.e., during exercise) your body must digest them into to smaller peptides. Research has shown that these are absorbed even faster than free form amino aids. For this reason gaspari nutrition uses a high quality whey hydrolysate that contains over 50% di and tripeptides as well as a large array of anabolic promoting ingredients such as a high dose of l-leucine (5 grams) to allow for unparalleled increases in athletic performance, skeletal muscle recovery, explosiveness and most notably, immediate increases in muscle size while you are still training.
