Use the TUDCA on cycle for liver support and also a comprehensive cycle support like cycle assist or Arimacare Pro. You need a SERM for PCT. Your options are Nolva, Clomid, or Rebirth if you want OTC. Also, running an AI after your SERM is a good idea with Epi to prevent rebound gyno. Letrone would be ideal for that. If you get a solid cycle support you can run the TUDCA at low dose through cycle and pct to save a few bucks.
