You got a very nice frame bro, work for 16 years payed of nicely. Now about your cycle, deca is not gonna take effect before week 5 so I would suggest you bump it up to 10 weeks to take the full benefit from it. If you do that you should also bump the test to 12 weeks so you don't have to battle with the 'deca dick'.
I'm looking forward to following your log, good luck.
