This is the second Gaspari Nutrition product that I have tried with Superpump 250 being the first. Gaspari has recently came out with an improved formula, Sizeon Maximum Performance, that makes it more of a complete intra-workout supplement. The original formula was mainly creatine based, but the new additions give you additional benefits including a whey complex and carb complex. As I have referenced in a previous review, consuming high glycemic carbohydrates and protein during your workouts will help boost your and gains and quicken recovery times. The only problem is that studies show that a certain carbs to protein ratio, 3:1, is most effective, and the Sizeon label does not tell you really how much of each complex is contained per serving. However, I think any additional carbs and protein during your training sessions will be beneficial. Here is a list of Q and A’s discussing the differences between the new and old Sizeon formulas.
Q: What is the difference between SizeOn Maximum Performance and SizeOn Pre-Contest?
A: SizeOn 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.” SizeOn Pre-Contest does not contain the OUTLAST complex nor pterostilbene.
Q: What is the difference between the new version of SizeOn and the original?
A: The new version of SizeOn contains high amounts of whey protein hydrosylate, leucine, along with more carbohydrates as well as pterostilbene to support insulin levels already within normal range. All in all, it is a much more advanced product based on cutting edge research.
Q: Can SizeOn 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.
The Sizeon Review:
Overall: 9/10
I really like the new Maximum Performance formula because of the additional complexes that make it a complete intra-workout supplement. I also like how the main creatine used in the formula is indeed monohydrate. I have read many studies that prove that monohydrate gives the same results as the more expensive hybrid forms. So the fact that they used monohydrate most likely kept the price tag down a little. I received great strength increases while I took Sizeon. My most impressive strength increase was in the barbell curl. I went from 6 reps to 13 reps of 135lbs during the 4 weeks I took this supplement. The reason I gave a 9 instead of a 10 is because since the end of the cycle, about 2 weeks ago, my strength has decreased a small amount which is expected after discontinuing any creatine supplement. However, I am still able to get 9 reps of the 135lbs so I am very pleased with a 3 rep increase in strength.
Taste: 8/10
I got the wild berry punch flavor and had no complaints. I have a sensitive stomach so it took a few workouts with the sizeon for the stomach to be completely “cool” with it.
Mixibility: 10/10
Just dump it in a water bottle, shake a few times, and you are good to go.
Price: 8/10
I train 4 times per week, the Sizeon cycle lasted me just over 4 weeks with about a scoop and a quarter for each training session. The recommended dosage is one scoop, but I am a big boy at 247 so I cheated a little. At about $10 bucks a week it was worth it.
What was your experience?
