Gaspari SizeOn (1632g)

Gaspari SizeOn Maximum Performance 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 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 - an insulin secretagogue - picked specifically to work in concert with Outlast carbohydrate blend. This powerful combination initiates and sustains muscle volumization and anabolism to levels never seen before in a sports nutrition product.
