If you need to cut for 5-6 months after a cutting cycle, then in my opinion you shouldn't of started a cycle at such a high percentage of bodyfat. My advice would be to come of the gear and get through PCT, then start to diet naturally until you are sub 15% bodyfat and then start a cutting cycle. How long have you been on cycle for? At 250mg per week I can't see your natural levels being shut down significantly so I would wait around a month after PCT to start your cut if you come off now. The only way to be certain is getting your bolods done.
