The only issue with andromix is that you can't adjust each hormone individually. I personally think it would be ideal for a first time tren user to use a little less to start, around 50-75mg EOD, to see how it effects them. You already know how test works in your body and masteron is pretty mild when it comes to side effects. I think that 50mg daily of prop and mast would be no problem at all. Just be aware of this as you go into the cycle. If you find that you experience insomnia, night sweats, mood changes, ect, it is most likely from the tren. 

ANYWAY, your test dose is low enough, that I would expect most people to be fine with estrogen related gyno, but since this looks to be a cutting cycle, I would use an AI to help control some estrogen, which will help with fat loss and a lean, hard look. .25mg adex EOD would probably be a good place to start. And up it some, if you need to dry out more. It wouldn't hurt to have some caber on hand. If you use it, .5mg 2x wk should be enough.
