SizeOn Intra-Workout Supplement

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 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 anabolic promoting ingredients such as a high dose of L-LEUCINE (5 grams) to allow for unparalleled support 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 - our patent pending and brand new insulin secretagogue - picked specifically to work in concert with our universally acclaimed and patent pending Outlast carbohydrate blend. This powerful combination initiates and promotes muscle volumization and anabolism to levels never seen before in a sports nutrition product. To top it off, we also included, 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!

Expensive, but well worth it. I mix this in to my intra & post-workout shake. The flavor(s) are wonderful & it mixes well. If you can get this on sale, stock up! I've been using this for several years now & feel that it really helps with my recovery.*
