cabergoline is some nasty stuff man, sooooo bad for you. i would never take that. i would up the dose on the deca and run it for less time, deca stays in your blood for ages and will get in the way of your PCT if you dont' give it AT LEAST 4 weeks to clear your system. same with the sust since i believe it has test enth in it. i would either cut out the deca or just take it for the first 5 weeks personally. i found deca to be pretty weak and all it really did was make my joints feel good and make me recover somewhat more quickly.
also, with the sust and deca you can double load your first shot. dont be afraid to take 1000mg of sust a week for the first two weeks actually, it takes so long to ramp up due to all the different esters that its really not an issue. sust typically takes at least 3-4 weeks before you notice it, if you double up on your first few shots maybe 2-3 weeks.
i will second these guys and say that 500-750mg of test and front load with dbol for 4-5 weeks is probably a better first cycle. deca sides are hard to diagnose and combat and you won't know which chemical to target if you get sides while your on both since the way you combat sides are totally different whether they are from the deca or the test. 750mg of test really isnt' that much if you are 200+ lbs too man, so don't worry about taking too much.
my advice is:
1000mg of sust for first 2 weeks, then 750mg a week for 10 weeks,
and your dbol for 5 weeks.
wait 4 weeks after your last test shot, start taking slightly more HCG and then start PCT.
keep the deca for your next cycle.
make sure you get some HCG and run it 250iu twice weekly throughout the cycle too, you will be sorry if you don't and the stuff is super cheap anyway.
nolva is much better for reducing potential gyno too, arimidex does little for this.
15-20lbs and maybe even reduce bf% should be pretty attainable if your diet is spot on and you work hard.
be sure to keep a log with pics for everyone too!
