1) Anavar should NOT be taken by itself. But yes with Testosterone . 2) yes 50mg is too low. Visit the nutrition section, nutrition is key. get that in order and you will see good progress. the only thing you need now is food and learn how to train properly. So visit the training section as well. I say this because you are asking how many times a week should you hit each muscle group. well that is up to you and how your body feels. so training and nutrition section are key for your progress, good luck and don’t give up.
