My husband was on the SWAT team and training hard for the SWAT Olympics. He began using Creatine as a regular supplement. This was a bad choice. At first, it was great and fine and he was doing well on it. But after a few months of regular use, he began to have health problems which I attribute to and believe were aggravated and brought on by Creatine. In fact, he still has those health problems. He is very healthy, not a drinker or smoker.
In the short term, it looked like it was a benefit, but in the long term it was not. He hasn't touched it again.
My personal advice: Run from it as far as possible and stay NATURAL in what you put in your body as much as you can!
