Magno Kidney & Electrolytes
eGFR on TRT
What the number means, why it moves on a protocol, and what people usually do about it.
What it is
eGFR estimates how well the kidneys filter, calculated from creatinine, age and sex. It is only as good as the creatinine that feeds it.
The range
TRT-aware target
over 90 mL/min/1.73
How to read the lab range
Above 90 is normal; 60 to 89 is mildly decreased on paper and normal for most adults; under 60 on two tests is kidney disease.
Why it moves on a protocol
- Anything that raises creatinine (creatine, muscle, dehydration) lowers eGFR without the kidney changing.
- Blood pressure and diabetes lower it for real over years.
What people usually do · not a recommendation
- A low eGFR in a big supplemented lifter is checked with cystatin C before anyone worries.
- Blood pressure control is the real protector.
How Magno reads it
Import the PDF or a photo of the report and Magno finds eGFR on it, keeps every test on one line, shows the change since the last one, and reads it against TRT-aware thresholds rather than the lab's generic range. The panel it belongs to, Kidney & Electrolytes, gets a written verdict with the probable causes and what people usually do.

Questions people ask
eGFR 75 on TRT, is that a problem?
Usually not. Creatine and muscle mass explain most of it. Cystatin C settles the question.
