More stable blood levels = better gains and less side effects. Also if its your first cyle, a full ml injection is probably gonna be a huge pain in the ass, literally.
Also, I would take more than 20mg of dbol, that isn't very much.
PCT would start week 15, not 14. And I would use Nolva 40/40/20/20 instead of Clomid. I feel great on Nolva, on Clomid I feel like a weepy emo bitch.
And you won't need to start Adex so high. Start with .25mg EOD and adjust as needed if you start to feel gyno or get too bloated.
