I would front load the test and keep the dose pretty high until about 4-6 weeks out (week 7-9). From there drop down the dose to one in which you feel you have very minimal water retention (100-250mg/wk for me).
Keeping the test high in the beginning would help you still make some gains while dieting down for the show, almost like a recomp. You're already at 11% body fat so getting into single digits isn't a big concern to you when it comes to time frame, especially when you have clen and var on hand.
I'd also try to get my hands on some ketotifen if I was you. Screw 2 weeks on 2 weeks off, you want to be as lean as possible so with ketotifen you'll be able to run clen straight for 4-6 weeks into the show. I've had buddies do it for 8 and see good results.
With regards to the Var. I'd run it at a high dose in the front end and the tail end of the cycle. In the beginning to assist with the recomp and the tail end for the thermo effects of Var as well as muscle hardening.
Only other thing I'd recommend is some Test Suspension to keep you full during the last week till contest. Maybe some Masteron for some extra hardness. Should really consider some Letro if not Adex to keep water down at the tail end.
Here's a little example of what I'm saying:
Week 1-7
Test @ 1000mg/wk
Week 1-5
Var @ 100mg/ED
Week 8-13
Clen ( Ramping up every week)
40/60/80/100/100/120
**Ketotifen every other week
Week 9-13
Var @ 100mg/ED
Week 7-13
Adex 0.25-0.5mg/ED (Adjust accordingly)
Other additions that would help:
Weeks 9-13
Masteron @ 100mgs/ED
Week 12 & 13
Test Suspension @ 100mg/ED
Drol @ 25-50mg/ED
Hope this helps man. Good luck and keep us posted.
