If you are thinking of coasting on test, then switch over to test e or test cyp after your cycle. Ive been coasting at 750mg of test cyp for months now.
Now, with that being said, Im not going to say its safe. Ive seen hormone doctors and coasting on test at higher doses than 200mg per month is not the best thing to do. You will most certainly run the risk of your natural testosterone being shut down permanantly. I shouldnt be doing it, but hey, I'll be ready for HRT in a few yrs anyway.
