Description

This combo combines Serious Mass weight gainer with pure creatine powder for NZ lifters who want serious gains in size, strength, and recovery. The stack gives you high calories, protein, carbs, plus creatine-powered performance support.

Why Choose Serious Mass Creatine Powder Combo?

  • 5.4 kg Serious Mass weight gainer – supplies high calories needed for mass gain.

  • 50 g protein per serve – supports muscle recovery and growth.

  • Pure creatine powder (5 g Creapure®) – boosts strength, power, and recovery.

  • Over 250 g carbohydrates per serving in the gainer – fuels high-volume training and restores glycogen.

  • Includes vitamins, minerals & glutamine – rounds out overall nutrition to support performance and recovery.

How to Use

  1. Mix 2 heaping scoops of Serious Mass with ~700 ml of water or milk using a blender or shaker.

  2. Take 1 rounded teaspoon (5 g) of creatine powder daily with water or juice.

  3. Use Serious Mass post-workout or between meals; use creatine consistently on both training and rest days.
    Pro tip: If full servings are too much at first, split the Serious Mass dose into two smaller shakes per day.

  • Strength & gym athletes – wanting both mass gain & creatine performance support.

  • Users with high calorie requirements – needing large carbs & protein intake.

Liv

I have been using Creatine for maybe 2 weeks now and I can definitely tell that I have put on some muscle mass and water. I guess if you are really into dieting and proper physical exercises than you will definitely see a difference. I usually weigh between 73-74kg without taking Creatine and daily exercises but since taking this I am able to hold weight on about 75kg and see more muscle definition. I mix this with my Oxyshred pre-workout as it is a bit difficult to be diluted in water. I recommend mixing it in with other drinks so you don't get to drink the leftovers in the bottom of your cup, which just feels like drinking sand. All in all I would recommend this product to anyone who wants to add to their gains and does not mind either dry scooping this or mixing it up with a shake or drink as it is tasteless.
