Anavar does give strenght and build muscle, with few sides but at a very expensive cost. No it's not dbols. Can't compare the strenght from 25 mg of each. Maybe at 50 mg we could but thats cost prohibitive for most of us. It will get you some permanent muscle. But again nothing sensational. 5 lbs from an anavar only should be seen as great.
Problem is, some folks here are looking for the best of both world, an all-in-one product. It doesn't exist. Everything comes with a price and risks. Some more, some less. Personally I place Anavar among my three fav. (others being Deca and sustanon).
