Mass Gainer


Canadian Protein Mass Gainer is not simply a weight gainer with loads of fat and poor carbohydrates, it is an extremely high quality weight gainer made with 100% Whey Protein Isolate, Micellar Casein and Whey Protein Concentrate as the main protein sources. If you're looking to bulk up, Canadian Protein Mass Gainer is one of the best weight gainers on the market.


What are Mass Gainers?

Mass gainers are supplements that are specifically designed to help individuals get into a calorie surplus and bulk up, with the assistance of proteins, amino acids, and other nutrients for example. These mass gainers in particular, are considered incredibly beneficial as they are made with micellar casein, whey protein isolate, whey protein concentrate, vitamins, minerals, and maltodextrin as the primary carbohydrate source. Bodybuilders when off-season, tend to use their off-seasons to bulk up and increase their muscle mass, allowing them to add size and mass to their frames, before they begin cutting and dieting down a few months later. In order to build mass however, you not only need copious amounts of protein, amino acids, and other nutrients, but you also need to be in a calorie surplus, and the bigger you are, the more calories you need, meaning the more food you would ordinarily need to eat. Mass gainers however, provide hundreds, if not thousands, of calories per serving, along with more than enough proteins, amino acids, and other nutrients. They basically function as anabolic meals high in calories, making life that much easier for people trying to bulk up. On top of that, mass gainers can also be useful for people who may simply be struggling to consume enough calories each day.

How do they work?

As mentioned, the primary use of mass gainers is to help people to bulk up and add muscle mass to their physiques, and they do this by providing large concentrations of proteins, healthy fats, amino acids, vitamins, minerals, and calories, with every serving. Protein plays a vital role in the growth and repair of muscle tissue, so obviously if you aren’t consuming enough, you simply won’t be building muscle anytime soon. The more muscle you have, the more protein and calories you need per serving, which is where mass gainers come into the mix, providing more than enough of everything that is required to initiate protein synthesis and keep the body in a constant anabolic state. In order to bulk up and increase muscle mass, the body has to be in a constant calorie surplus, and sadly, the calories should ideally come from quality sources, which is why mass gainers are so useful. Each serving provides hundreds, even thousands, of calories, making it much easier for individuals to hit their daily macro targets. Not only do they assist with muscle growth, they also boost overall health and well-being, as they are enriched with vitamins and minerals that nourish the body and provide numerous health benefits.

What are the main benefits of using Mass Gainers?

Some of the main benefits associated with mass gainers include:


The primary reason why mass gainers are so popular is the fact that they’re so convenient. For people trying to bulk up, consuming enough calories each day can get tough at times, especially from whole food sources. One or two mass gainers per day however, will help a person towards their daily calorie targets, without having to choke down vast amounts of food.

Full of nutrients

As mentioned, mass gainers are also enriched with proteins, amino acids, vitamins, minerals, and other nutrients, making them very healthy and very beneficial for us. Not only are you getting plenty of protein per serving, you are also increasing your daily vitamin, mineral, and nutrient intake as well, making the supplements very healthy.

Muscle growth

Obviously the main benefit associated with mass gainers is the fact that they assist with muscle growth and repair. In order to build muscle, the body needs calories, it needs proteins, and it needs amino acids, all of which are provided here. To keep your body in a constant anabolic state, this mass gainer is made up of a blend of different proteins, including casein protein, so it will keep you in an anabolic state even during the night, as the protein is much slower to be absorbed.

Other benefits include:

  • Muscle growth
  • Increased strength
  • Convenient
  • High protein per serving
  • Slow and fast release protein blends
  • Full of nutrients
  • Boosts the immune system
  • Quality high calories per serving
  • Great taste
  • And more...

How and when should they be consumed?

For best results, experts recommend consuming 1 – 2 mass gainer shakes per day, either with milk or water. You should consume these shakes as a meal, so they should not be consumed with whole foods, as that can hinder the protein absorption rates. Simply add 150 g (3 scoops) to 500ml liquid, give a good mix, and enjoy. To increase the protein and calorie content, and for a thicker consistency, combine with milk instead of water.

Health Canada Recommended Dose (powder): Adults: 3 Scoop(s) 1 time(s) per day. Mix product well in 2-6 cups of liquid (water, juice, etc.) immediately before consumption. Store in a cool, dry place.

Mass Gainers VS Whey Protein

Although whey protein also assists with muscle growth and repair, the main difference between the two is the fact that mass gainers are made up of different protein blends, plus they are enriched with carbohydrates and healthy fats. Mass gainers are designed to function as a whole meal, whereas whey protein is designed to function as a supplement. Whey protein is absorbed much quicker than a mass gainer, plus it contains far, far less calories, and should ideally be used individually, at a different time of the day, to a mass gainer.

What can they be stacked with?

For people looking to bulk up and build muscle, mass gainers stack very well with: tribulus terrestris, pre-workouts, BCAAs, Whey Protein, Omega 3's, and Multi-vitamins.

Mass Gainer Strawberry Milkshake

Useful and really tasty. I put it in my smoothies when i'm too busy. This allows me not to put too much pressure on myself when I don't have time to cook and to reduce periods of catabolism during the day.
