You are very confused my friend.
A test booster is just that. It increases your NATURAL testosterone levels. When you stop taking it, there is NO NEED for Post Cycle Therapy. Your NATURAL testosterone levels simply return to their normal levels.
A steroid, on the other hand, replaces your natural testosterone, causing your body to drastically reduce its own natural test production. When you stop taking it, there is no natural test being made, so estrogen and cortisol are elevated. (over simplification)
You are wasting your money by buying Novedex xt or an aromatase inhibitor such as adt, 6bromo or 6oxo.
In fact, many people use test boosters DURING PCT from a steroid cycle. That would be unwise if the products themselves required PCT, no?
Unfortunately, the title of your thread has caused some of the members that have replied to you to misunderstand you. There is no need for PCT from a Test Booster like Diesel Test Hardcore.
