1 gram is a high amount of test, expecially for a 5th cycle. i found that at the 1gram point, side effects get more dramatic. instead of going that route, you would be much better served to add in a 2nd injectable compound. 3cc of sust with 2cc of deca or 3cc of EQ would give you more gains and probably have far less androgenic sides like acne and body hair growth. the beauty of stacking steriods is that when you combine them, the effect becomes much stronger than what it would have been when just taking more of one steroid.
if all out mass is your goal, test/deca/dbol would be much better than just taking more test.
test 750mg EW
deca 400mg EW
12.5mg arom EOD to ED, depending on your needs
PCT starts 2 wks after last injection
