Sure you can keep your gains from oral only cycle if you are gonna do what you say,, however I didnt like your
PCT, not at all. We have much better options right now.
Dont go crazy with the dosages, with real Dianabol - methandrostenolone - , you will even see huge gains on 20 mg a day, watch out for your
Liver values,,, most importantly search this site a little and have better
PCT otherwise you will fail.
If you do everything right, your expectation is very possible
hope this helps
