Depending on your goals and your current situation ( body fat %, level of training) Off the top of my head without knowing any of that I would say a 12 week Test, NPP, with a Dbol up front for 6 weeks would be a good next step. NPP is deca so not sure about your situation deca stick with you a long time and is detectable forever and a day after you stop. Also it tend to shut you down pretty hard. But if you are experienced with a good PCT you should be fine. Worried about detection and shut down? Then Go Test, EQ for 16-20 weeks and if your relatively lean like under 12% BF you could add Anavar the last 6 weeks. If your not lean then save your money as Var won't show much on a fat frame. But there are downsides to this one as well, being on for that length of time, blood quality becomes a concern, high BP as well.
Your best bet is to keep reading and studying to see what would be best for you and your current situation. If you research enough the answer will be obvious what is right for you.
