Keep in mind with Deca it could initially help your joints but when you come off your joints could get worse. So be aware of that. It's important to still train with control. And don't overtrain.
I would do the Anavar at 50mgs a day. i've done that before. You can actually push it to 8 weeks if you want. Make sure you're eating solid no junk food and no fast food.
Better make sure you're using N2guard with it. N2guard is great for oral steroids and also injectable steroids. It will help keep your organs safe and your liver in good shape.
