When it comes to choosing a quality gainer, the ratio of protein to carbs is the key to a lean gainer that will put on muscle instead of fat. Most gainers are overloaded with sugar and typically contain poor quality protein sources. Pro Gainer utilizes premium protein sources such as whey, casein and egg - protein sources that digest at different speeds to insure an ongoing supply of amino acids will be circulating in your bloodstream throughout the day.

Pro Gainer doesn’t stop there; it also provides slow-burning, lower glycemic carbs, MCTs, fiber, a full-spectrum vitamin-mineral complex and digestive enzymes. Of course, Pro Gainer tastes amazing – after all, if you’re going to drink it, you should enjoy it!

Pro Gainer Highlights:

650 Calories per Serving: The key with calories is that you want to gain muscle, not merely “weight” which implies the weight gained may be fat as much as anything else. If you have a hard time gaining muscular weight, often the problem lies in the amount of quality calories you’re taking in every day. The answer is to find the consistent daily calorie intake where you start to gain and then stay at that calorie level. Adding one shake a day can begin to produce results but for many, there may be a need to add 2-3 shakes a day. You can be sure that with Pro Gainer, you’re adding quality calories with a high ratio of protein to carbs.
High-Quality Multi-Source Proteins: Protein builds muscle. So why buy a gainer that’s overloaded in sugar with inferior protein sources? Pro Gainer uses premium quality, high biological value proteins that feature different rates of digestion which creates a time-release effect.

Complex Carbohydrates: Pro Gainer uses slower burning complex carbohydrates to provide the energy your body needs. Unlike many gainers, Pro Gainer is low in sugar to avoid potential fat gain from the insulin spikes, such as those brought on by gainers that typically contain high amounts of sugar. Each serving of Pro Gainer provides just 85 grams of carbs, with only 5 grams of sugar as well as 4 grams of fiber.

Fat: Pro Gainer utilizes a blend of MCTs and other healthy fats to promote quick energy with little chance of fat gain. Pro Gainer is low in fat with only 8 grams per serving.

Micronutrients: One serving of Pro Gainer provides 26 vitamins and minerals – these are the nutrients your body requires to perform at its best. Think of vitamins and minerals as the best “health insurance” you can buy!

Taste – So what does it taste like? With several great milkshake-like flavors, you’ll think you’re indulging in a decadent ice-cream shop shake every time you mix up a serving!
