How to Use Your System

We designed our products to be easy-to-mix, match, and modify — so your body gets what it needs to prepare, perform and recover.

  • Daily Dose

    Mix 1 scoop with a product in your personalized Gainful system or add to at least 8 oz water, or beverage of your choice — as often as needed or as recommended by a healthcare or performance professional.

  • Recommended Use Case

    Ideally, use Creatine or Collagen 30-90 minutes before or after exercise. Mix with any of your personalized Gainful products. Fiber is best post-workout.

  • Repeat

    The journey is just as vital as the end result. Progress is the point. Enjoy the gains as they come.
