deca isnt that good for a first cycle, its very very inhibitory, add to that it takes around 45 days after your last injection to be significantly out of your system its really not a good choice for a 6-8 week cycle. Test E is even kinda long half-lifed for a shorty like this... so heres my advice.
Test prop around 100mg ed for 6-8 weeks with a good AI like femara at 0.5mg ed. Throw some dbol in there to start off if you want. Get your pct in order too. Just my 2 cents. Goodluck!
