I would not suggest going into a contest on Test Cyp because you will most likely carry some water.
Why not run a 12 week cycle and add in a few more compounds...something as easy as this:
w1-9 Test E
w1-12 Masteron E
This would give you the size part of things I assume you are looking for in the beginning and then allow you to drop the test a few weeks out from the show and go into the show on mast/var which will illicit a dryer look than test/var.
I'd also use adex through the cycle and a proper diuretic pre-contest. Proviron probably wouldn't hurt as well...
I'm a fan of halotestin/masteron for pre contest drugs. You can look into those...I have yet to use var, but it sounds like something I might like.
Good luck and is this your first show? Cycle history, age, stats,etc will be helpful as Bonez said.
