Gaspari took Sports Nutrition to the highest level with SizeOn, the original intra-workout creatine drink. 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. SizeOn now uses a high quality whey hydrosylate 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 increases in athletic performance, skeletal muscle recovery, explosiveness and most notably, increases in muscle size.* Furthermore, Gaspari Nutrition researchers have harnessed the power of pterostilbene - our brand new insulin secretagogue - picked specifically to work in concert with our universally acclaimed Outlast carbohydrate blend. This powerful combination initiates and sustains muscle volumization and anabolism.* To top it off, we also included LOLA™ our cutting-edge, ammonia scavenging amino acid salt of L-Ornithine and L-Aspartate to help battle fatigue.* The bottom line is that Gaspari Nutrition has once again outdone itself and yet again redefined what an intra-workout supplement should be - a category of product we created years ago!*
