You are right that 5 weeks is very short, especially since your test is enanthate which takes a couple weeks to peak and a couple more for the magic to happen.
You will be ending your cycle right as you start getting the business end of it, for short cycles look toward short esters. Prop ftw.
As far as PCT your clomid dose is a little low, I think people tend toward 100-150mg/day; its not as powerful as nolva (and makes me break out something fierce.
You will have to wait for the test to clear your system before beginning pct, and again with long ester test, this can take 2-3 weeks following your last injection. Stopping the Dbol won't affect this, all the drugs need to be out of your system before PCT starts or you will whiff it.
