NO! What your planning to use is great but your time frame is off! You need to ryn that at least 10 weeks same dose would be fine. If you do it for just 6 weeks it will just be kickin in when you get started. Also you could add an oral like dbol or tbol to start gainin day 1.
And yes I think you should use an anti-e it will keep you from getting bloated at least, also have some dostinex on hand in case of issues from the DECA
Good Luck
