It sounds like you are GTG, bud. I'm not a huge fan of the PH's on the market. Some of these compounds can be more harsh than traditional gear. That being said, they are very common and many people are using them on a regular basis. Sounds like you have a good time frame, 4 wks on the PH combo. This will at least minimize stress on your body that might come about from longer term use, I know about the oral PH "tren" products and I once tried Epi. Not familar with the m-sten, but the other 2 are more on the mild side, as far as being liver toxic. Still, it wouldn't hurt to use some milk thistle or liv-52 while on cycle. Personally, I use liv-52 through an entire cycle. With your test dose, you shouldn't need a ton of AI, but some will still be good to keep more of your test from converting to estrogen. If you are using adex, .5mg 2x wk would be a good place to start. If you need more, you can always increase the dose. 

The only other option you may want to consider is using HCG at 250iu 2x wk through the cycle to help with recovery. It isn't needed, but it may help. Do keep in mind though, that those who are estrogen sensitive may get a reaction from HCG. The AI will help with that, but it is important to understand. 

PCT starts 2 wks after your last shot of test
