I'm on 40mg per day now and my strength is good, but as far as putting on size with a mild drug, you're better off with deca in my opinion...Deca and anavar would be a decent light run now that I think about it.
If you're bridging like I am, it would be hard to tell if you keep the strength because when you go back "on" your strength should go up anyway. When I come off the anavar, I'll be going on about a gram of test and 300mg of deca, so I'll never know if I would have kept it.
