Taking a look back, Gaspari Nutrition shocked the Bodybuilding world by introducing the original SizeOn. This was groundbreaking because, for the first time, an intra-workout creatine drink was perfected.

As science advances, Gaspari Nutrition has decided to revolutionize the Sport's Nutrition world yet again and reformulate the most anabolic product yet; SizeOn by Gaspari Nutrition.

Reformulated for Perfection

One of the recent scientific advances has shown that when digesting protein, your body breaks it down through a process known as "hydrolyzation". During this process, di and tripeptides are absorbed and used by your body to start the muscle-building process. Modern science has shown that during physical exertion, your body must break down these nutrients into smaller peptides; causing a problem.

Due to this problem, Gaspari Nutrition has decided to incorporate Whey Hydrolysate. Clinical research has shown that Whey Hydrolysate is absorbed even faster than free form amino. Whey Hydrolysate contains over 50% more di and tripeptides, along with many more anabolic compounds to have you putting on slabs of muscle. One such anabolic compound found is L-Leucine, which increases performance, enhances skeletal muscle recovery, boosts strength, and immediately increases visual muscle size during training.

Along with incorporating the powerful Whey Hydrolysate, Gaspari has discovered a patent-pending compound called pterostilbene. This anabolic compound is an insulinogenic secretagogue that is used to be in combination with our patent-pending Outlast carbohydrate blend. The purpose of this combination is to sustain muscle volumization and enhance anabolism to a new level unlike anything before.

As if it couldn't get any better, Gaspari decided to take it up another notch and include LOLA™. This potent compound is comprised of L-Ornithine and L-Aspartate; to fight off and delay fatigue.
