The PCT question can be answered
here, point number 6 where it says Post Cycle Therapy.
I don't see HCG or an AI in your cycle plan. Those will likely make the cycle more pleasant and productive - some doctors in the US will prescribe both for TRT level doses. Getting through the cycle without problems will also likely make PCT easier. Their use is also covered in the above link.
As for Trib, with the proper PCT protocol specified in the link, you won't need it. It would be a waste of money in that case, imho.
