You need to stay strong and try to stay off until December. Your body needs the break, and if you don't give it one, then your next cycle WILL NOT be as successful as it could have been.
I'll say this, it is a myth that you always lose all of your gains after a cycle, but in my opinion keeping 100% of them after every cycle is nearly imposable for most people. Most people can expect to lose some of their size and strength after a cycle, however, if you run a good PCT and if your diet and training is on point, the majority of this size should be simply a loss in water.
