If you do this type of thing, just take arimiex, not clomid + arimidex. They probably have no additive effect on boosting T levels and there is just more possibility for side effects. Also, there is tolerance to clomid I belive but not with arimidex that is why clomid is better for PCT, not sure on that point though. Arimidex alone has been shown to roughly raise and lower, respectively, testosterone and estrogen around 50 percent in nomral men. However, the problem with this is that this is just in the serum, the systemic circulation. It is possible that in specific sites like the bone and especially the brain tissues, the estrogen levels are lowered to a undesireable level. It is not known though but quite possible.
6-8 weeks of it probably wouldn't hurt under 9 out of 10 scenarios, in my humble opinion, but it would be expensive and produce very slight benefits. It will definately do something to your head that you might not like. It might help you to get leaner if you have problems with bf and you engage in an aggressive, smart cardio program.
Regardless, IF you are young and you have not done juice yet but you are contemplating it, this arimidex alone idea is certaintly a far superior idea to juicing. You shouldn't juice until you are 23-22 at the least if you are smart. Otherwise you invite possible developemental problems(never mind all the other problems you invite with juice, cardioascular and hepatic and the like). I don't know if this applies to you.
My basic opinion, it might help you but you will probably start taking it for a long period of time and this will be very bad for your health.
Especially if you are a recreational drinker, drug user this thing is a bad idea. Local estrogens in the brain (at normal male levels ofcourse) are important neuroprotective agents. High T/E ratio can cause problems with your brain goes the hypothesis. T causes enhanced potential for neurotoxic insults in the abscence of E.
