Reviewed March 2026

I suggest this to customers who want to put on size but are sensitive to artificial ingredients or lactose. The fact that it uses whole foods like oats and quinoa makes it stand out from heavier, more traditional gainers.

It digests easily and provides a solid mix of fast and slow proteins. If you want a cleaner approach to gaining weight, this is a reliable daily shake.

Good fit for

  • Muscle building
  • Heavy lifter
  • Strength training

Not for

  • Milk allergy
  • Vegan diets
  • Soy allergy
