Full description


Gaspari Nutrition takes sports nutrition to the highest level with SizeOn - The Ultimate Hybrid Intra-Workout Amino Acid & Creatine Formula. The original SizeOn became known as the King of Creatines and by utilizing the latest advances in clinical research, this award-winning formula is better than ever! SizeOn contains high-quality whey protein hydrolysate, which is clinically proven to absorb even faster than free-form amino acids. SizeOn also boasts a premium creatine formula, high-performance carbohydrates, a high dose of L-Leucine (4 g), and many more anabolic-promoting ingredients. SizeOn contains the revolutionary ingredient L-Ornithine-L-aspartate (LOLA), which has been shown to reduce ammonia and improve psychometric function. L-Ornithine-L-aspartate is able to reduce high blood ammonia levels induced either by ammonium chloride or protein ingestion. Furthermore, LOLA decreased protein breakdown and stimulated protein synthesis in muscle.*
