    great stuff, been using it for ages
  • 5/5
    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.
