"The objective of this part of the study was to determine
whether creatine supplementation could increase the amount
of creatinine in human urine specimens even after hyper-hydration. People undergoing mandated drug screening sometimes consume a large volume of water prior to testing in an
attempt to wash away the presence of illicit water-soluble drugs
in the body. The tests showed that over the course of an 8-h period the creatinine concentration declined consistently without
any significant elevation even in participants who took creatine"

Thoughts about this study regarding using creatine to mask a diluted sample The dilution thread above suggests using creatine will mask the effects of dilution by raising one's creatinine levels. I found a study that seems to suggest creatine supplements have no effect on creatinine levels. Any thoughts?
