JAP, you are my hero, that is my favorite cycle. Awesome gains and great pumps. You might even want to throw in some FINA when you get done with the D-bol. It will harden you up like never before. Clomid is used to jump start your nuts after a good cycle. You won't need it till the Sust is just about clear of your system. Sust has a 15 day period in your system so, you won't need it till 15 days past your last shot. As for the anti-estrogens, with 500 mg Sust /week you will probably not need it till week 4 maybe even 5, if water retention is an issue then, yes, start them right away. They may however decrease your gains. I like to start them when my nipples start to itch and not before. I have gone as much as 7 weeks before I needed them. Hope this helps. Clomid during a cycle, not at all necessary!
