For those taking creatine

[HealthMan]

How many days before blood work stop taking it so it doesn’t mess with creatinine results? I haven’t used creatine for years. Will give it a go again but my creatinine is usually on the higher side (very muscular) so don’t wanna mess with creatinine results

Different thought on testing kidney function...try the Cystatin-C w/EGR test, better for muscular men that can be skewed by the higher Creatinine levels we have.
Search the forum under my name and/or Nelson's name for more info on this test.

Yup. It is just a regular blood work for Defy. My kidney function is fine. Just don’t wanna push creatinine higher because of creatine supplementation

I tried 72hrs w/o Creatine (and gym work) and would fast 12hrs prior to those tests and I couldn't tell if that was making any difference, I thought it did but no solid indicators if that worked. Sometimes my Creatinine would come back under the max and sometimes it was over for no discernible reason.
