Personal experience and my own research.

The bottom link also states that "
Creatine supplementation does not appear to increase endurance performance and may impair it by contributing to weight gain." If you don't mind the extra weight then it isn't an issue if you are a body builder. I gained about 5+ pounds of weight I didn't care to have and on the run it was just more baggage. I'd much rather be as lean as possible without the bulk up. It boiled down to do I want the extra mass and if so do I want to carry it on the run. That's where I was coming from.
You will not lose muscle by discontinuing creatine supplementation, however, you will experience a decrease in strength. -

You got me there to some degree. However you will have to stop taking it before say OCS. You'll have the muscle but will you be able to take the strength drop once you detox?
There was one such case where an otherwise healthy user contracted kidney disease. It was a rare case, but it's something anyone thinking of taking should know.
Some reports showed that kidney, liver, and blood functions were not affected by short-term higher amounts or long-term lower amounts of creatine supplementation in healthy young adults. In a small study of people taking 5–30 grams per day, no change in kidney function appeared after up to five years of supplementation. However, interstitial nephritis, a serious kidney condition, developed in an otherwise healthy young man, supplementing with 20 grams of creatine per day. -

That link is where I did the bulk of my outside research on it.
Also I added a link in my first post on this subject. Good stuff. I feel that for all the benefits there are just too many inconsistent studies and from the way
I felt after using it, I just don't feel a need to continue using it, especially for endurance improvement. That's just my experience with it.
This is all good stuff in this topic and hopefully educational to someone thinking of trying the supplement.
