Anything you take that acts as test in your system will inhibit your natural test production (i.e.shutdown). You have alot of research to do, but you are in the right place. There are supps to take while ON to lessen your shutdown (HCGenerate is a nice one). You also want to become acquainted with Post Cycle Therapy (PCT), which should include the Unleashed Combo and some Clomid. Make sure you look into on cycle support too. And needless to say, a multi vitamin, creatine, and a protein powder. Once you have a handle on those things you will want to post your stats and goals, and how you work out and how long you have been doing it. There is a standard Test e or c only first cycle that you will see in your research, which you will probably want to consider at that time.
