I heard from several people, that Xtreme Tren could really mess up your libido in the last couple of weeks of the cycle and it takes a while to get it back. However the gains are supposedly good. If so inclined, I would try Havoc (Epistane) for 4 weeks 20/30/30/40 with Cycle support to help liver and lipids. As for PCT, Nolvadex (Tamoxifen) for 4 weeks. If can't get Nolva, Primordial Performance makes Testosteron recovery stack, they claim works just as good as real ancillaries.
Also, it is a good idea to get your blood test (lipids, liver values, hormonal panel) done, prior to running the cycle in order to establish a base line
