Depending on your weight I would say between 200-300mg test-e/ weeks.
If you are real big add deca 100-200mg/week.

If you want to continuously make good gain, 500mg test/week with a 200mg deca.

I believe that testosterone can be run even in high dose for a prolonged period of time without issue if you control your E2/blood pressure/ hematocrite and of course as long as your prostate is alright.

Adding deca at these dose,(with what doctors as told me), should not cause any health problem as a part of TRT(or cruising) protocol.
As long as estradiol is under control!

Keep in mind that there is no turning back from it. Once you go on you are most likely never going back off again...(while feeling good anyway...)

Your life, your choice...
But I strongly advice you to know exactly what your doing cause if you dont and something bad happen you wont know what to do or how to deal with and it will make the future a real pain in the ass...
Inform yourself as much as you can, and take your time, its a lifelong commitement.
