Endo says hcg is useless when used with test?

I know that wasn't part of the test prior to TRT but I am going to check back on past yearly blood tests and see if it may have been checked. If not, would I know if those levels are low on this upcoming test.

The problem is that TRT will suppress your LH levels further, so any tests from hereon should come up in the low range. Again, that's why baseline labs are important.
