Our ThoughtsExtreme Mass by International Protein is a great mass gainer product, especially for those with a fast metabolism who usually struggle to pack on the kilos. Its easy enough to make a gainer product when its filled with sugars and fillers - but to do it cleanly, utilising high quality clinically approved ingredients, is a whole different story! Extreme Mass ticks every box - including taste, its every bit as good as your childhood milkshakes.
