In the latest MESO-Rx original article, @PeterBond discusses the problem with the use of traditional kidney function tests in anabolic steroid users and more useful alternative tests.
"Estimating the GFR based on the serum creatinine concentration is notoriously unreliable in muscular individuals. Since muscle is the primary storage site of creatine in the body, muscular individuals will carry around more creatine in their bodies. Consequently, the rate of creatinine production is also higher. As such, with similar clearance rates, the serum creatinine levels will also be higher. As a result, these formulas will underestimate the true GFR. Another issue that arises in this population is one caused by creatine supplementation."

Measuring Kidney Function in Anabolic Steroid Users
The kidneys are responsible, among other things, for filtering the blood and producing urine. They do so by creating a filtrate from the large amounts of
