Designed for serious athletes and gym enthusiasts, this 3.59-pound grape-flavored powder delivers clinically backed creatine and amino acids to fuel explosive strength and size gains during training. ## Description Gaspari nutrition took sports nutrition to the highest level with the original sizeon, the original intra-workout creatine drink. There wasn't any doubt it represented a serious innovative leap forward in the creatine category. The original sizeon formula clearly demonstrated its effectiveness in a clinical setting and quickly became known as the king of creatines. As clinical research advances, so does gaspari nutrition which is why sizeon has now evolved into the ultimate hybrid intra-workout whey hydrolysate creatine formula. Once again gaspari nutrition raises the bar even higher in the sports nutrition industry!your body requires that proteins from whole food, whey isolate, casein, etc., be broken down in a process called "hydrolyzation". This is an integral process which allows di and tripeptides to be absorbed and utilized for numerous processes including muscle building and repair. The problem is that while your muscles are starving for these nutrients (i.e., during exercise) your body must digest them into to smaller peptides. Research has shown that these are absorbed even faster than free form amino aids. For this reason gaspari nutrition uses a high quality whey hydrolysate 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. Review: It works, simple as that - Been using SizeOn for years, and know several serious bodybuilders and power lifters that use it as well. I personally use it diluted by using a half scoop per about 16oz of water. Otherwise its too sweet and syrupy. As for my experience with it, I use it for my intra-workout drink, particularly when doing my upper body split. Just gives me that "extra" energy and spark I need without feeing like a stimulate. Results? I routinely hit my personal best lifts on a regular basis. Ironically my girlfriend started using it too, although she's not a big fan of the taste. Bottom line, it gets the job done which is all I'm after. Review: Effective size and strength gains - I tend to be going towards these intra workouts . This works great. Great to drink during my workouts and noticing I’m putting good size and muscle on. Good energy. Flavors taste good. The only thing that has me concerned is the cancer and reproductive warning on the back. It sounds worse then it is really. I looked up the p65 warnings. It said it’s possible something in this has come across something then can cause those issues. Not for sure though. It’s just a warning they had to put in there by law. If anyone knows more on this please share thanks. ## Features - Speeds up Protein Synthesis & Muscle Force Recovery.
