what's the problem with Test/EQ/Tren in one cycle?
Nothing at all, would be an awesome stack! But when its your 2nd cycle he would be better off running the test & eq cycle hes currently on and then, following correct PCT and time off running the prop and tren together.
I know there is alot of information on here you are new to but try and read up as much as you can about steroids and correct post cycle therapy. Good luck witht he cycle, test & eq is a great combo!
