Just by taking an anti-estrogen you won't raise your testosterone levels - all you will do, is lower your estrogen. However, you should not do so in excess, since you still need proper estrogen levels in order to function properly. If you want to recover your natural testosterone production, you need to run a mini-PCT with clomid, nolvadex, HCGenerate ES and some Ostarine Mk-2866.
As for the oral cycle, I would not recommend doing more than ten weeks of any oral steroid, and you would definitely need a good liver supporting supplement, such as N2Guard. In fact, I would dare to say that N2Guard is the best liver supporting supplement you can get these days, since it has so many ingredients in it, including TUDCA. Initially, anavar should not cause any sort of mental or emotional issues. However, if you already have some pre-existing problems in that regard, you should act with caution.
Yup, anavar will not cause any mental issues. However some people get kinda depressive while on clomid, so keep that in mind.
For me, whenever I feel gloomy while on it, I just try to remember that its just the compound affecting me, and things are not actually that bad, haha
