Never heard of anything close to this, and personally I think the doctors are wrong...but interested in your thoughts:

Seen it a while ago, already fired off a letter to the editor about irresponsible reporting and bad fact checking and I'd reccomend everyone else do the same. Elevated levels of creatinine, not creatine, are what's associated with renal failure. The guy was sufferring from Rhabdomyolysis, which is a rare but well documented condition where the muscles simply break down and dissolve. It can happen as the result of injury or severe overtraining, there have been documented cases. The black urine was likely hemoglobin and myoglobin from his dissolved muscles, the other symptoms were likely caused by some severe misuse of growth hormone or some steroid.
At 5 grams a day there's no way in hell creatine would cost 50 dollars a month, he's probably lying about the cost to cover up spending the money on the compounds that really caused his problems, or he's the worst shopper on the planet. I also know of no way in hell a person's creatine levels could jump that high, much less jump from 3500 to 9000 overnight. And how is that level determined? What unit? What standard? What's normal? Creatinine, if they did confuse them, is considered a problem over 1.5-2.0, 3500 would essenitally mean your kidneys had dissolved.
And contrary to the article's claim, there are studies on creatine use, long and short term. It's only caused a problem with the kidneys in people who have preexisting renal problems, and there's not one documented case in medical history that I have found of creatine causing Rhabdomyolysis. Training at his level, serious abuse of steroids or GH or other compunds however can explain his symptoms and there's plenty of support for that in the medical literature.
Keep using creatine and ignore this moron, though if it ever comes before congress you know this schmuck will testify, and no one, repeat no one will question the vercity of anything he says.
