You should honestly probably research things a bit more before you start your cycle. Everyone should ideally have at least a working understanding of the HTPA and how exogenous steroids suppress it via the negative feedback loop. The only thing you can take that will make your testosterone levels go up is testosterone -- or something that converts to it. However, it's not YOUR testosterone that will increase -- it will actually be shut down -- it's just that you are injecting several times more than what your body would normally produce. So if you were taking a compound like testosterone that gets 5AR reduced to DHT, then you WOULD want to use finasteride to reduce the amount that got converted. However, taking epi or Trenazone, or Hdrol, etc., will shut down your natural T production, and since none of those compounds convert to DHT, you will have very little DHT floating around in your system to attack your hair. I'm a little concerned too that you might not have a good PCT lined up. Could you say what you're planning for that?
