For those of you who want to build some serious mass, SupplementSource.ca is the number one destination for premium, high-quality mass gainers in Canada. Our collection offers extremely potent mass building protein blends from major reputable brands.

Benefits of Mass Gainers

Bulking up takes some serious effort including high-intensity strength and resistance training. It also requires the right type of nutrition.

Bodybuilders and athletes rely on our premium mass gainers to nourish their bodies from within by combining high-quality protein sources with complex carbs to truly supplement their intense exercise regimens. No amount of meat, dairy, poultry, fruits, or vegetables can be equivalent to the concentrated protein sources that are critical to building mass.

SupplementSource.ca offers amazing mass gainer products: From Perfect Sports HULK, our lactose-free 1000 calorie dense gainer, to Mutant Mass, a superior quality protein blend. All of our high-quality protein supplements are designed for the most hardcore athletes, strongest bodybuilders and anyone who aspires to be one.

When you’re consuming any of these supplements, rest assured that they will facilitate your intense efforts in the gym by helping you put on some serious bulk:

  • Allmax QUICKMASS - For those of you who want to gain mass, QuickMass is a scientifically formulated rapid mass gain catalyst that provides nutrient-dense calories, increases calorie activation, and is easy to absorb by the body.
