Macro-packed mass gainer protein that will help gain huge muscle size!

While some are quick to judge a mass gainer solely on the caloric value, 24 Hour Nutrition must educate its customers that not all calories are created equally! Certainly not when it comes to ON's Pro Complex Gainer. The difference with this product is the derivation of its protein sources, sitting at a higher percentage than some competitors. Also containing essential minerals, vitamins and complex carbohydrates, ON has managed to create a gainer that remembers you are looking to put on size, not just fat!

Key Factors

  • High quality lean gainer formulation

During the 24 Hour Nutrition Team's research for Pro Complex Gainer, it didn't take long for us to marvel at the effort that has been made to ensure the highest quality gainer – with 7 superior proteins! As we are sure you've experienced before, some mass gainers leave you feeling bloated or heavy. This is not the case with Pro Complex Gainer. It's easy to drink and even easier to mix. A great characteristic of all ON products!
