Optimum Nutrition Pro Gainer



What is it?

  • Putting on size requires a balance of heavy training and quality nutrition. Because everyone's a little different, some have a harder time packing on muscle than others. PRO Gainer™ is a high-protein formula delivering calories that count during recovery. Each shake provides ample supplemental protein, carbs, vitamins and minerals to build on the amount you're getting through a balanced diet of food. Use PRO Gainer™ as your post-workout recovery shake and/or high-protein meal between meals.
  • At 650 calories per serve, this would be a perfect weight gainer to begin with in adding some extra, high quality calories to your diet!

Optimum Nutrition Pro Gainer Benefits

  • 650 calories per serve - not a crazy high amount of calories! Perfect to add, clean lean muscle mass.
  • 60g protein - extremely high protein content to ensure you're enhancing your muscle growth and muscle recovery
  • A blend of 5 different protein sources - fast, medium and slow digesting giving your body a sustained release of nutrients
  • 85g of clean carbs - not full of cheap sugars like most other weight gainers out there
  • Tastes like a delicious milkshake!

When should you take it?

  • With any weight gainer supplement, it's important to take it on top of what you're consuming in regard to your nutrition and not as a substitute. For example, do not replace your breakfast meal with a weight gainer shake. Have your weight gainer shake in addition to your breakfast meal.
  • Because of the high calories per serve, post-workout immediately after training and a second time throughout the day such as mid-morning would be ideal.
  • Use more water than what you normally would due to the serving size.
