Burke DG, MacLean PG, Walker RA, Dewar PJ, Smith-Palmer T. Analysis of creatine and creatinine in urine by capillary electrophoresis. J Chromatogr B Biomed Sci Appl. 1999;732(2):479-85.

Key Finding:

Creatine is found in the urine of subjects ingesting creatine monohydrate as an ergogenic aid. Significant amount of creatine is excreted after ingestion. It can also be seen that with a higher dose, a larger absolute amount of creatine is retained, even though the fraction of the dose excreted is larger.
