When I run test,deca, and dbol I run a 16 week cycle. I stop the deca at week 14 and the dbol at week 6. The only oral I would run 8 Weeks is anavar. When running deca you need to have caber on hand to deal with prolactin issues like deca Dick.
Yeah ... it's better, though, for a 2nd cycle, I'd prefer you run only the Test at no more than 500mg/wk ... if you REALLY want to run the oral, then run DBol for the 1st 4 wks at around 35-40mg/day. Most ppl say ED, but I prefer to run it Mo-Fri, resting my body (liver) over weekends. And remember to take on cycle support like HCGenerate and drink enough water.
Honestly, the Deca thrown in there is too much IMHO. Drop it for now ... you'll have enough time in your cycling time in future to run it and be better prepared. From just the DBol and Test over 12 wks you'll see decent gains guaranteed so long as your diet and training is sorted.
