Don't waste time on orals in your off season. You're better off just increasing the injectables.
Will add - I agree with this. Do I think the stress on your body from orals are worth it - no. For someone who is competing in strength competitions or BB contests, they are great, but if you want to keep your gains you are much better off increasing the injectables. 3 injectables is enough and you don't even need to increase the dosages anyway - you are already taking 1200 mg of injectables a week.
Everyone knows I am conservative, but all you are doing is adding stress to your organs at the end of a cycle and sure you will look great for a while, but you won't keep the gains from the orals. At least that was my experience when I could take orals.
There are exceptions - there is a very wise lady on this thread that is limited to specific PED's because she is female and may need orals plus she competes. Different situation than the average guy who wants to grow at the gym.
If you compete, save the orals for getting ready and no, I do not compete - I am going 100% by what coaches I know recommend.
Each to their own, I'm no one's gatekeeper. If you want to use orals, do it. I tried many including T-bol and my liver enzymes went through the roof but I felt great and loved it for the few weeks before I got my blood work back. At that point I threw them out. Same with Oxandrolone, or any oral - too much stress on my body. Lipids start to go in the wrong direction too.
Further, even if I could take them now, I wouldn't I would rather increase my Primo and NPP by a little and expect to keep a lot of the growth.
