This is more of a psycological dependance at this point bro. If you were to cut your dose way down and give your body a break, you should be able to keep most of what you have gained. I would strongly consider taking 8 wks to cut back to HRT dosing, around 200mg every wk of test, along with some arom for E control. Let your body reset and when you go back on, you will be able to make more progress. I'm sure that at this point, gains have stopped or slowed way down. You need to have some down time. Even if that means not coming off all the way, HRT will allow you to recover in many ways. Get your cholesterol looked at as well as your kidney and liver function. There are guys that stay on for years and stay healthy, minus their ability to produce natural test or have active sperm, but they cycle up and down. You can't stay rampped up for 2 years and expect to maintain health. Give yourself a break, make sure you are healthy and then com back. I promise you will make better gains in the long run
