DIM, liver support (generally a good idea when taking a number of any meds), blood pressure support. These are the main 3 I take regularly only because of TRT.
Then there's things like Methyl-Folate, methyl-b12, P5P, some hgh supps (mostly supps that increase dopamine like sam-e/p5p/ low dose deprenyl which is not a supp though).
Are you looking into TRT or full HRT?
