Liver

AST on TRT

What the number means, why it moves on a protocol, and what people usually do about it.

Updated 2026-09-26 · Part of the Magno guides

What it is

AST is a liver enzyme that also lives in muscle and heart. It rises with ALT on liver stress and on its own after training.

The range

TRT-aware target

under 40 U/L

How to read the lab range

Labs quote up to about 40 U/L. AST higher than ALT after training points at muscle; ALT higher than AST points at the liver.

How Magno reads it

Import the PDF or a photo of the report and Magno finds AST 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, Liver, gets a written verdict with the probable causes and what people usually do.

Questions people ask

AST high but ALT normal?

Almost always muscle. A high CK confirms it.

This is how experienced TRT users read the number and what they usually do about it. Every decision about your protocol belongs to you and a clinician who knows you.
