Gaspari took sports nutrition to the highest level with SizeOn. 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 Maximum Performance now uses a high quality whey hydrosylate that contains over 50% di and tripeptides as well as a large array of muscle building 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 – 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 sustains muscle volumization and anabolism to levels never seen before in a bodybuidling supplements product.

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!

Frequently Asked Questions

Q: What is the difference between SizeOn Pre-Contest and SizeOn Maximum Performance?
A: SizeOn Maximum Performance contains the revolutionary OUTLAST carbohydrate complex for maximal performance in the gym and recovery and it contains pterostilbene – our patent pending, naturally occurring insulin secretagogue – which helps to push those carbohydrates (and amino acids and other nutrients) into skeletal muscle cells to maximize glycogen synthesis, cell volumization and myogenesis. This formula is geared towards an athlete looking to "bulk up as fast as possible." Size On Pre-Contest does not contain the OUTLAST complex nor pterostilbene.

Q: What is the difference between the new version of SizeOn Maximum Performance and the original SizeOn?
A: The new version of Size On contains high amounts of whey protein hydrosylate, leucine, along with more carbohydrates and the insulinotropic powerhouse pterostilbene. All in all, it is a much more advanced product based on cutting edge research.

Q: Can SizeOn Pre-Contest only be used by bodybuilders or can athletes looking to build muscle mass and enhance their recovery use it as well?
A: SizeOn can be utilized wishing to speed their recovery, build muscle mass, and increase performance whether in the gym or for athletic competition.
