You said they are the same thing. I never said they are the same thing.
I am stating fact not assumptions. Creatinine is the direct metabolite of Creatine and is cleared by the kidneys.
Creatinine is a break-down product of creatine phosphate in muscle, and is usually produced at a fairly constant rate by the body (depending on muscle mass). In chemical terms, creatinine is a spontaneously formed cyclic derivative of creatine. Creatinine is chiefly filtered out of the blood by the kidneys (glomerular filtration and proximal tubular secretion). There is little-to-no tubular reabsorption of creatinine. If the filtering of the kidney is deficient, creatinine blood levels rise. Therefore, creatinine levels in blood and urine may be used to calculate the creatinine clearance (CrCl), which reflects the glomerular filtration rate (GFR).
You want them to measure less Creatinine ? You stop dumping Creatine into the system and retake the test. Worked before, I will find out next week if it works again.
