I don't know man, but 16 weeks seems something short of a prison sentence to me. not that is bad, good, right or wrong but IMO 16 weeks, I wouldn't. personally myself, I wouldn't run gear for 16 weeks.
shorter time with time off between will allow for adjustments- EX- if something is given at 8am, maybe it would have been better at 11 am for various reasons. maybe the dose could have been lower or higher.
since you don't know if its a good idea or not, why not run 8-12 weeks, break and then start over?
nothing wrong with jumping into the pool, as long as its not the shallow end
