Anavars can be run for up to 4 months with few or no side effects. It will not add much poundage- but it does transform your body to make you appear much larger then you did prior to taking it. The pumps are comparable to that of deca and the fat burning effect is unrivaled even by a gh / test stack. Vars are relatively easy to get these days- the down side is that they are expensive - and you need to take a large quantity for maximum results. you would need either 200 5mg or 400 2.5mgs- depending on your connect the 5mgs will cost you up to $200 per 100 pack. You should probably take between 40 and 50 mgs a day- there is no reason to pyramid your cycle- and as long as you dont stay on these for 4 months it should not effect your liver at all.
Vars are great and have proven to build lean muscle mass in HIV patients who led sedentary lifestyles- imagine what it could do for you - a healthy person that trains>
