Creatine Kinase on TRT
What the number means, why it moves on a protocol, and what people usually do about it.
What it is
Creatine kinase leaks from muscle when it is worked or damaged. Lifters run high CK all the time; it is what makes ALT and AST look like a liver problem when they are not.
The range
TRT-aware target
under 200 U/L
How to read the lab range
Lab ranges top out around 200 to 300 U/L. Two days after a hard session it can read in the thousands with no harm.
Why it moves on a protocol
- Training in the two or three days before the draw.
- Muscle mass; bigger people run higher.
- Statins and dehydration add to it.
What people usually do · not a recommendation
- No training for 48 hours before a draw so the liver panel means something.
- Above 5000 with dark urine is rhabdomyolysis; that goes to a doctor.
How Magno reads it
Import the PDF or a photo of the report and Magno finds Creatine Kinase 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, Metabolic, gets a written verdict with the probable causes and what people usually do.

Questions people ask
High ALT and high CK, is my liver damaged?
Probably not. ALT and AST leak from muscle too. A normal GGT with a high CK says muscle, not liver.
