Is 1.29 creatinine is high?

Just a bit: A normal adult male range is 0.6 to 1.2 mg/dl. Keep an eye on your blood pressure and your blood sugar.

It depends: If you're a well-muscled or just a husky / big man, this is normal. When i was lifting weights every day, mine ran 1.6-1.7. You're a person, not a bunch of numbers. You'll even find labs that will give an adjustment for people of african descent "because black people are more muscular." this is subscience. Stop worrying.
