Nolva is fine during a cycle, but a-dex is what I would use...more efficient IMO.
How much T-3 are you planning on using during thus cycle? Have you used it before? 10 wks of T-3 is a chunk, you might consider running it only the last 6wks. I have run it for an extended period before, but at the beginning it was at a very low dose. When I use tren, it has a tendency to lower thyroid levels and raise prolactin, so I ran 25mcg for 8wks and then the final 6wks I ramped up to 150mcg ed and back down. But in the case of your cycle I don't see the need to run it that long. If you have never used it before, you do not know how it will effect you once you come off...everyone is a little different. Me, I do have a slight rebound when coming off of it, and for a while, fat gain is very easy, so I have to be really carefull until things sort of "normalize." If you run it too long, and you are unaware of how it will effect your system, you could end up being one of those people that rebound really bad and come out looking like crap...your call.
