Sus and deca will just blow you up like a baloon mate. You'll hold lots of water and lose it all afterwards. Why not try some test 350 and equibol for a first cycle? Good for size and no nasty sides.
For the record i didnt get many bad sides from tren, bit angey (its the only sted that does it to me) and occasionally the cough but its only for a couple minutes at jag time.
