As previously mentioned, tren is not recommended for a first cycle but let's answer this as though you are going to do it regardless...
I am personally running Tren A for my first time right now, going in to my second week. I had read about running Tren A at a 2/1 ratio against Test P and was running it this way for the first 4 days. I had some insomnia (woke up every day at 3 a.m. after going to bed at 10 p.m.). I felt fine other than that, no night sweats, not overly agressive but on Friday I decided to run the ratio at 1/1 versus 2/1 and I have had uninterrupted sleep since.
Everyone's results are different and you may have to adjust to find your sweet spot.
The aromasin should be run throughout your cycle and I would suggest caber for the Tren as well. I have both and am running them, not just keeping them on hand.
I would suggest using HCG as well while running the Tren as you're going to be shutdown hard.
For PCT, if your last shot is on a Friday, on Monday I would begin running Nolva. Doses have been argued and if you research you will find all kinds of opinions on best way to run but the most standard is for four weeks starting at 40mg a day the first two weeks and 20mg a day for the next two weeks.
