I'm seeing a growing number of reports for decreased oral AAS efficacy when used alongside UDCA/TUDCA, even from fairly experienced and educated members.
I can't find much about UDCA's effect on orally administered steroids metabolism, besides this study on oral contraceptives that actually shows slightly enhanced bioavailability:
Please post your anectodal experience (this should go without saying: only if you can compare pretty much identical cycles with/without UDCA) and other relevant studies on the matter.

Ursodeoxycholic acid does not affect ethinylestradiol bioavailability in women taking oral contraceptives - PubMed
Co-administration with UDCA does not affect the bioavailability of EE2 in healthy volunteers, indicating that contraceptive efficacy is not affected.
