Serious Mass MEANS SERIOUS CALORIES

To gain weight, you need to consume more calories than you expend. For many aspiring to hit their calorie goals and put on size, a highly active metabolism, weak appetite or on-the-go lifestyle can make it a real challenge to get enough calories from food alone.

suitable for those:

  • Training longer and harder to gain more muscle
  • Finding it difficult to consume enough calories through food alone
  • Finding it challenging to gain weight regardless of your dietary intake
