ALT on TRT
What the number means, why it moves on a protocol, and how it sits with related markers.
What it is
ALT is the liver enzyme most specific to the liver, and it also leaks from muscle after training.
The range
How to read the lab range
Labs quote up to about 40 to 50 U/L. A mild rise after training is common; a large rise, or one with GGT rising too, points at the liver.
Why it moves on a protocol
- Heavy training within two days of the draw.
- Alcohol, high-dose paracetamol, some fat burners and other medications.
- Fatty liver after a long bulk.

Questions people ask
ALT 60 after leg day, is that the liver?
Often it is muscle. GGT and CK help tell them apart: a normal GGT with a high CK points at training.
When is a high ALT a concern?
A large or rising ALT, a rising GGT next to it, or any yellowing, dark urine or pain is one for your doctor.
