Tren is an awesome compound, but it DID shut me down pretty hard. Granted, I ran it for twice as long as you are planning, but I could still tell that the shutdown was intense. I recommend either grabbing clomid to go with your nolva for pct, or pick up aromasin and toremifene from ManPower (best PCT I've ever run). Running it for only 6 weeks is a good idea, though you WILL be tempted to go longer. Don't. Stick to your guns, especially since this is your first experience with tren (and cycling in general). How long are you planning on running the test for? I would say 10 weeks is the sweet spot that will allow a speedy recovery which is huge because you want to keep the majority of what you earned right?
Apology accepted bro, though I don't think you offended anyone. I was just giving you some friendly advice that I was given at one point (and then again, and again, until I finally got it.)
EDIT: Manpower Nutrition is a sponsor here on the board. They sell high quality capsules of research chemicals to use on your rats for research. Great reputation and great products. Check them out in the sponsors section. Also, I meant aromasin, not arimidex. Many reasons why aromasin is a better product. Once you've done some research on it I'll give you an outline of how to run the aromasin and torem for PCT.
