What You Need To Know About Mass & Weight Gainer Protein

What You Need to Know About Weight Gainers

Weight gainer protein is designed for people who struggle to gain weight through regular meals alone. Perhaps you've got a speedy metabolism, or maybe you're an athlete trying to bulk up. Whatever the case, these body weight gainer shakes are built to help you hit your calorie goals without needing to eat constantly throughout the day.

Shop Protein Power for Weight Gain

Weight gainer shakes are high-calorie supplements formulated with a balance of proteins, carbohydrates, amino acids, and fats to support healthy weight gain and muscle growth.

Unlike your typical protein powder, body weight gainers pack a much higher punch, containing between 400–1250+ calories per serving. The protein content (a mixture of WPI and WPC) promotes muscle growth and repair, while carbohydrates provide an energy source for workouts and recovery.

Not sure where to start? Our Guide to Mass Gainers breaks down how to choose the right one for your goals.

How to Choose the Right Weight Gainer

  • Calorie content - match the gainer to your overall calorie goals, not just the highest number on the tub
  • Protein per serving - make sure it's enough to actually support muscle growth, not just bulk calories
  • Carbohydrates per serving - the right amount fuels training and recovery without excess
  • Quality of fat sources - some gainers rely on low-quality fats and fillers, so check the label if this matters to you
