Anavar has the least amount of sides of any of the AAS. It is used in children as well as AIDS patients and burn victims. I has the same potential sides as any of the rest but the chances of having them are far less. It works extremely well when used alone and can be used to gain mass or cut depending on the diet and training that you do while taking it. I am on week 11 and have gained 9# of lean mass and lost 4# of fat give or take. I was sick and out of the gym for 2 of those weeks.
