Stay on. Test is very cheap especially at the dosages you are using. Recovery isn't a problem for me personally, I can't speak for you though.
No need for all that PCT crap, just stay on low dose test until you are ready to do another run. Honestly, anything under a gram isn't really blasting. You shouldn't have to worry about your health on 300 mg a week of test e, if you do well your genetics must be exceptionally poor. You have a good base naturally, so you don't need to run a lot to look great. Id stay on that 300mg test e, and maybe add something like deca or masteron depending on your goals. 3-400 of either will do you right.
