SizeOn Max Performance by Gaspari Nutrition is a muscle building protein powder supplement for bodybuilders who want to have more energy to workout longer. The protein powder contains amino acids, protein and creatine, but it is the addition of a glucose based proprietary blend that increases energy, not a stimulant. This causes an increase in calories which makes the protein powder even less suitable for weight loss.

List of Ingredients

SizeOn Max Performance: Vitamin C, Thiamin, Riboflavin, Niacin, Vitamin B6, Folate, Vitamin B12, Pantothenic Acid, Calcium, Phosphorus, Magnesium, Sodium, Potassium.

Product Features

The SizeOn Max Performance protein supplement is no different than other protein powders created for bodybuilders. The supplement basically contains protein, creatine and glucose. These three ingredients work together in the body to feed the muscle more protein. When the muscle is worked in the gym, glucose will carry the protein to the muscle for energy and repair. This is often when bodybuilders take carbohydrate supplements before or after intense workouts. As for the dieter, there is no reason why the SizeOn Max Performance will increase metabolism or weight loss. The supplement could be used as a meal replacement shake, due to the inclusion of so many vitamins and protein, but the body tends to react better to vitamins taken in food form as opposed to supplement form. Creatine is not an ingredient aimed at women, so the meal replacement shake would be best taken by a male dieter.

SizeOn Max Performance sells for $48.99 per container. Each container holds 24 servings with a one-serving per day dosage.

  • Bodybuilders may see increased muscle mass from taking the supplemental protein powder.


  • Dieters do not need creatine to lose weight.
  • There are no stimulants or fat burners in SizeOn Max Performance.
  • The protein powder supplement is more expensive than other protein powders.
  • The protein powder will not decrease appetite substantially because it contains glucose.


We do not suggest using SizeOn Max Performance for weight loss. The protein powder is created with creatine for bodybuilding and increased muscle mass and not weight loss. There are no stimulating ingredients or appetite suppressants, so the dieter will not see much benefit from taking the supplement. A better choice could be a green tea or chromium supplement for increased fat burn and decreased appetite. Supplements with these ingredients are safe for use by both men and women aiding in reducing body weight and increasing metabolism.
