Glad you came to the site. You were getting some bad advice in regard to deca and winny.
Var can assist you in getting to you goals. I am assuming your goal is to lean out since you mentioned a weight loss drug.
I am a believer in basic science. What that means is you take one compound at a time. That allows you to see how your body reacts to it. Later you can run the first substance with a second and you will note how the second compound effects you. If you jump right in with both you don't know which is doing what!
That said I would choose the weight loss drug or Anavar. Not both.
I may be way off in direction here so please post up your overall goals and I can be more detailed with what you are looking for.
