no benefit at all imo . the reason is is because , as far as what i've seen , is that injectable anavar only comes in a water based solution . That means your chances of having an injection go bad and become a bacterial infection are increased by 1000 fold. water based injectables are notorious for infections.
run oral Var for 6 weeks . 100 bucks says your liver enzymes won't even elevate a couple points. doctors prescribe oral anavar for muscle wasting all the time , and don't concern themselves with liver issues from doing so.
Dbol, Adrol, etc.. is a whole other story. but Var is really not hard on the liver
