Gaspari took Sports Nutrition to the highest level with SizeOn, the original intra-workout creatine drink. As technology advances, so does Gaspari Nutrition which is why SizeOn has now evolved into the Ultimate Hybrid Intra-Workout Whey Hydosylate Creatine Formula. SizeOn now uses a high quality whey hydrosylate that contains over 50% di and tripeptides as well as a large array of muscle 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. Furthermore Gaspari Nutrition researchers have harnessed the power of pterostilbene - picked specifically to work in concert with our universally acclaimed and patent pending Outlast carbohydrate blend. This powerful combination initiates and sustains muscle volumization to levels never seen before in a sports nutrition product. To top it off, we also included LOLA™, our cutting-edge, 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!
