Time off between Blasts

So I just finished 15 weeks of test and deca, 900 test and 600 deca a week. Do u guys take extended time off, between Blasts.

I was going to drop down to 250mg a week test, for a few weeks before the next cycle.

Since I'm old and and don't have to worry about having kids any time soon. Should i take time off at lower dose, or just keep trucking along...

Thanks
