Review: Optimum Nutrition Pro Gainer Complex James RAugust 14, 2014Mass GainersSupplements0 Comments Nutrition Breakdown Calories per serving: 650 85 g carb 60 g protein 8 g fat Other 20% DV Cholesterol 20% DV Saturated Fat 6 g sugar The ON Pro Gainer Complex is a premium mass gainer supplement for those who want a balanced high-qualityproduct. Many mass gainer supplements on the market today are pumped full of excess carbohydrates, sugars, and alarmingly high levels of cholesterol or saturated fats. The ON Pro Gainer complex stands out from the rest because it contains a high percentage of protein while keeping bad things like cholesterol and saturated fats to a minimum, which is important if you are planning to take this supplement everyday. The ON Pro Gainer Complex also contains a large number of micronutrients (vitamins and minerals) which dispels the need to take additional multivitamins. It mixes quite well with any beverage and comes in a variety of flavors. Pricewise, this ON mass gainer is a little on the pricey side, but I believe that if you are planning on consuming this product everyday, it is well-worth the investment to buy something of higher quality during your bulking phase.
