I think that's actually a good thought process.
If you've been lifting regularly, perhaps take a week off to rest, then after a week back in the gym start your cycle. A little rest before the big thump works well for me (at least it used to). Also, your gonna want to lift as hard and heavy as you can while under the influence of "performance enhancing substances". You can always take another week after pct is complete...
Agree, if your gonna be on you should be able to push it. If you can get on a good roll, read injury/pain free training cycle where things are overall going well in your life especially with work, relationships and over all stress is relatively low. These rare periods are when you should be pushing to be the best you can be.
If your hurt, just lost your job and the GF/wife is causing you headaches probally not the best time to think about a big cycle, cause you will not be into it 100%
