Serious Mass Facts

Serious Mass Gainer contains 50 grams of protein per serve from a blend of fast-acting and slow-release sources.

Combined with a massive 250g carbs to fuel muscles, restore glycogen and enhance nutrient delivery, this product will have you stacking on kilograms in no time. The powerful nutrients glutamine and creatine offer the means to rebuild glycogen and ATP that much faster, supporting explosive strength, power and stamina, and the means to build muscle mass faster.

Serious Mass Calories

This product provides 1,640 calories per serve when consumed with low fat milk, these are simple and convenient calories that taste simply amazing. No one questions the nutritional authority of whey protein, which is why it's the first ingredient used in this product.

Whey protein is loaded with naturally occurring essential amino acids, which are potent stimulators of muscle protein synthesis. Protein synthesis is the creation of new muscle tissue protiens. This means more gains for you. Whey protein is particularly high in an essential amino acid called leucine. Leucine is a stimulator of mTOR, which is the spark that ignites muscle protein synthesis.  

Whether you're a novice or professional, Serious Mass Gainer will get you to your goal weight faster. You should notice some strength gains along the way too.
