Pro Complex Gainer by Optimum Nutrition

Optimum Nutrition's Pro Complex Gainer is a protein-carbohydrate complex for gaining muscle mass.

The product is intended for those who find it difficult to gain muscle mass by eating ordinary food. It supplies only high-quality amino acids and glycogen, and helps to recover after a workout. Weight gainers are not some prohibited substances, but an ordinary sports supplement designed to even out the imbalance in the diet. Simply put, this is a cocktail of quickly digestible macronutrients for those who are tired of choking pasta and meat six times a day.

The gainer is suitable for beginners who have just begun to engage in bodybuilding or fitness. Athletes of a higher level can also take it for their own purposes.

Balanced Supplement Composition

Optimum Nutrition's Pro Complex Gainer contains more than one type of protein that is quickly absorbed and ceases to “nourish” your muscles in an hour. This is a complex of fast and slow sources of amino acids. For 7 hours after taking the supplement, the body will receive small portions of amino acids to restore strength. Additional intake of amino acid complexes is not required with this gainer.

Carbohydrates are represented by maltodextrin. It is an energetically beneficial source of carbohydrates. It allows the body to do hard work for a long time. Therefore, Optimum Nutrition's Pro Complex Gainer is suitable not only for bodybuilders, but also for power lifting and weightlifting enthusiasts.

Carbohydrates and proteins are in the additive in a ratio of about 1 to 1, a serving provides 650 kcal and about 60 g of carbohydrates and proteins. Fat is only 5 g, which simplifies the absorption of basic macronutrients. The complex contains vitamins and minerals, which allows you to make gainer full snack or meal.

The supplement does not contribute to the accumulation of fat, as it does not contain excess calories that can not be spent on muscle recovery. Unlike other gainers, it is “lighter” by about 350 kcal per serving. This does not affect mass-gaining qualities, because all Optimum Nutrition's Pro Complex Gainer macronutrients are in high bioavailability and are absorbed qualitatively and completely.

How to take Pro Complex Gainer from Optimum Nutrition

The basic rules are as follows:

  • Take every day;
  • For hardgainer, the dosage is three servings;
  • Those who wish to simply recover after a workout are enough 1-2;
  • "Admission course" does not exist, the gainer drink the entire mass-gaining training cycle

On training days, you need to drink a serving after, and one at a time - in the morning and in the afternoon. Hardgainers can enjoy a cocktail just before bedtime. One serving is a measuring spoon of powder dissolved in 400 ml of liquid. Some people prefer to breed a gainer with milk or juice, but this is not necessary. Even if there is no shaker at hand, and there is only plain water and a mug, you can prepare a delicious cocktail, because the powder dissolves perfectly. The drink is not sugary, but moderately sweet and thick. Difficulties with the reception of most users do not arise.

Tip: to speed up the recovery processes after exercise and strength growth, you can add a serving of amino acids and creatine to the drink.


This product is of high quality. The reviews indicate that typical problems for the gainer do not arise - bloating does not torment after ingestion, flatulence and diarrhea are not present, the drink is absorbed, like any ordinary food.

The authors of the reviews note a pleasant taste, especially for the products "Chocolate", "Vanilla". But not everyone likes berry-fruit options. But many argue that the gainer tastes like a strawberry smoothie and is easy to drink.

There are forums and negative. Some athletes criticize the pricing policy of the company, and say that this product is not available to the average person. While protein products are becoming more expensive in ordinary stores, this statement remains controversial. It has long been estimated that the cheapest sources of high-quality macronutrients are just in the cocktails of sports nutrition.

The second point is the lack of expected results. Here it is necessary to take into account the factor of high expectations. Many people think that with the gainer banks they will look like professional athletes, but this is not so. The result is due to genetics, the style of training and the presence or absence of errors in observing the sports regime. Just drinking a weight gainer, lifting dumbbells anyhow, and eating the rest of the time with instant noodles is a bad strategy for gaining muscle mass. Only observing all the components of the training regimen, the right diet and taking quality supplements will give a result.
