all you're really doing is adding more prop to the sust. i guess thats o.k. but if this is your first cycle i would save it for another, possibly a cutting cycle with some tren (later on) sust 500mg week and d-bol will give you good gains size and strength and i don't think 200 more mgs of test a week will make a big difference. good luck on whatever u decide looks like you should make good gains so bust a-- in the gym and keep us posted.
