Are you trying to add quality size to your frame but are finding it difficult to get in enough calories to see any noticeable changes in lean muscle mass due to your quick metabolism? You’re not alone. There are plenty of people out there who can eat seemingly everything in sight and still not make the gains they desire.

The clean carb matrix found in MASS is truly setting a new industry standard. Mammoth did away with the heavy sugar formulas you find on the market and created a matrix that includes ingredients such as quinoa, sweet potato, and rolled oats. We’ve tossed in some healthy MCTs as fats and you have the most advanced and complete mass gainer formula available today.

Mammoth MASS is a game-changer in the mass-gainer category. The term “mass gainer” has been dragged through the mud for over a decade due to the current state of the products available. Essentially, they have been loaded with unhealthy sugars and cheap carbohydrate sources; all in the name of producing a mass gainer that is slammed with as many calories as possible per serving.

Mammoth MASS was created to help those wanting hard gains and those looking to put on MAMMOTH size in a manner that helps maximize lean muscle tissue growth while also minimizing increases in body fat. We’ve done just that with mouth-watering flavours you’ll enjoy every time you mix yourself a shake.


Here’s the great news… ANYONE. It doesn’t matter if you’re an elite athlete, student, business executive, bodybuilder, power lifter, strongman, weekend warrior, or someone who just wants to add some quality size to their frame, Mammoth MASS is for YOU!

The precise revolutionary formula found in Mammoth MASS provides clean ingredients you can feel good about consuming – none of the junk and high sugars you are accustomed to seeing in similar mass gainer products. It's for that reason that so many people have made the switch to Mammoth MASS – to take in the quality calories and ingredients needed to put on the size they desire.

  • The real highlight of the Mammoth MASS profile comes in the form of its clean carb matrix. This clean carb matrix is made up of oat fiber, sweet potato powder, quinoa powder.
