Not worth it right now man. Let your body continue developing. Your natural test levels haven't even peaked yet. Also, you just started training. You will have years of natural growth ahead of you so there is really no need for any PEDs. What you can do is work on eating right and exercising. That is where all the results come from anyways. PEDs just give you that little extra above what you can naturally achieve. If you want to take anything, get some creatine.
