I've been using a lot of different creatine products over the years and this has become a mainstay in my stack. You tend to think it's not working if you don't get that bloat but once I stopped using it I could see a big difference. I didn't lose size but I did lose strength and I found I was getting much more sore after a workout. This is also a thermogenic and it does a good job of keeping the fat off. I've used several bottles and I have no plans to change. Great product!!
