Hey bro, thanks for the questions and thanks for doing your homework, reading up on the QA. If you want to use this cycle to lean down, you might want to use the anavar at the end of the cycle instead of the start. You can start the cycle with just the test and eq. As you focus on diet and cardio, you can continue to get leaner and improve body fat. Then in the last 6-8 wks, add the var in, to push your look that much further. 8 wks if fine with var. I wouldn't go past that though. Its considered to be a "safer" oral, but it still will effect your cholesterol, just like any other oral steroid. And also, if you want to use Milk Thistle, I would dose it at more like 1000mg ED.
As for HCG, some guys like the way it feels. It may have helped you with your libido issues on the deca cycle, but as for recovery, if you are normally on HRT, there is no need for trying to maintain natural production. For an HRT patient, natural production does not exist! If you do decide to see what you think about HCG, I'd use 250iu 2x wk, through the cycle
