Simple answer; don't.
You prob don't want to hear that, but at such a young age, you are already in the process of producing the most testosterone you will in your life. In no way am I promoting the use of AAS/PH, but wait until you are at least a little older. Though you can run different compounds/cycles/stacks safely, you must do your research. You need proper PCT (post-cycle therapy) after, to help get you back to your normal levels. If you don't, there are numerous side effects that can occur, one of them being gyno (male breasts). The increase in test/decrease in estrogen during the cycle, leads to the reverse effect once you've stopped the cycle, which is where PCT comes in to help return them back to normal levels and control the rebound. A SERM is needed for PCT for all AAS/majority of PH's.
