    This premium mass gainer formula also contains glutamine, an amino acid known to enhance recovery and boost growth hormone levels for faster muscle growth.[3] With 5 g fiber, complex carbohydrates, and a whopping 60 g of protein, Pro Gainer increases muscle glycogen storage after exercise for higher muscular size and capacity.[4] With a high content of vitamins and minerals in addition to the mass-gaining compounds, Pro Gainer provides the safest and healthiest way to increase lean muscle mass.

    Very nice weight gainer, taste.... meh

    I’ve been trying to put on weight (lean muscle mass) over the last 18 months. The last 3 months of that time I’ve been using Pro Complex Gainer instead of Syntha-6.

    I’ve been gaining about 1.5 – 2lbs more a month with Pro Complex Gainer, but it was tough to switch because I was taking Syntha-6 and it just kills Pro Complex Gainer as far as taste is concerned.

    Not sure if the person who commented above about the great taste has tried many proteins. I have, and I give Pro Complex Gainer a C grade on taste, but definitely a solid a A+ on results.

    Good Gainer

    I am a hard gainer and I have been lifting weight for 15 years, I know what to do to gain weight, but some of the routes I was taking in the past in order to gain weight was just too risky for my health so I decided to just go back to the A and start taking weight gainers. All weight gainers will give you some water weight, some are better than the others so I would say Pro Complex is a good gainer compare to some of the other garbages out there, like TruMass. Again weight gainers will put some weight on you but the question is what kind of weight? Water weight, Fat, big belly. Again this is a great gainer compare to the others. I will be on this gainer for six months and then cycle it off, shed all the water and hopefully keep some weight.

    Best gainer for the money

    Unless you’re a body builder you don’t need one full serving. If you use a quarter of a scoop or a half a scoop, the amount of servings for the money is unbeatable. Great stuff. Will buy again.

    Good protein and carbo source

    I bought this for my 16-year-old son. He is a soccer player, but is too skinny, even for soccer criteriums. I tried, and have a wonderful taste. So far, he does not look very tired as before.

    Which one do i get?!

    I eat a lot everyday and also work out a lot but i find it very difficult to gain muscle as i am skinny, i am not sure which supplement i should buy, i am stuck between the Pro Gainer and the Mass Gainer, which one would be best for me to gain muscle and size without getting fat?

      Re: Which one do i get?!

      Pro Gainer and Mass Gainer are relatively similar when taking a glance at the ingredients. However, there is a difference in calories, carbs, fat, and protein as well as a few ingredients listed. The body needs to take in more calories (food consumption) than it expends (exercise) in order to put on weight. If you aren’t able to take in as many nutrient-dense calories as you are expending, it is recommended that you take Serious Mass. If you feel you are hitting your caloric needs but need a few extra nutrient-dense calories with high protein, it is recommended that you take Pro Gainer. No matter which mass gainer you decide on, these formulas contain high amounts of carbs, fats, and calories which tend to increase fat stores along with muscle mass.

    Pro Gainer

    this product flat out delivers. there are about 3 things i look for when rating a product like this one. Number 1, does it do what it claims it will do? absolutely. Number 2, does it taste good enough that i dont have to force myself to drink it? it sure does taste alot better than most. Number 3, how well does it mix? very damn well, i do not have to use a blender at all, i can mix it in a shaker or in a mug with a spoon. everything else like vitamins and minerals are a plus. Overall im very satisfy with this gainer.

    Optimum Nutrition Pro Gainer

    Overview

    This product is a powerful weight gaining supplement that supplies your body with complex carbohydrates, protein, medium-chain triglycerides, and essential nutrients in order to help promote muscle growth and prevent gains in fat.

    Directions

    Drink 1-2 servings in between meals or take a serving 30-60 minutes after working out. You can also take this supplement 45-60 minutes before going to bed.

    Warnings

    Take only as directed. Individuals who are diabetic or hypoglycemic should not use this product without first consulting a doctor.

    Featured Ingredients

    This supplement uses 7 high quality protein sources in addition to complex carbohydrates and dietary fiber to help you get bulked up and reach your body composition goals.

    Calcium – This natural element is commonly found in dairy supplements and is one of the major components involved in the mineralization of teeth and bones.

    Whey Isolate – Whey Isolate supplies an ideal ratio of key branched chain and straight chain amino acids to promote rapid muscle growth and development.

    Casein – Casein is a protein derived from milk that supports protein synthesis for faster muscle growth and greater strength. Casein helps prevent muscle breakdown, allowing you to avoid the muscle loss that often accompanies bouts of intense exercise.

    Glutamine – Glutamine is the most abundant amino acid found in muscle cells. Supplementing glutamine helps replenish muscular capacity for greater endurance, faster recovery, and higher strength. Glutamine also increases growth hormone levels for faster muscle growth.

    Complex Carbohydrates – Complex carbohydrates provide a long-lasting source of fuel to support muscle building and protein synthesis during and after exercise.
