What are your stats and what are your goals? Test can be stacked with almost anything, my favorites are staking it with EQ or Deca, also once and a while Tren. I'm stracking it right now with Anavar.
Tren and dbol are both good for strength/aggressiveness... Dbol can only be run for a few weeks.... and tren has some crazy sides.... so make your choice accordingly.
With your stats and at 5'11' and only 185 I would say you need 1-2 more years of natural training. Not to offend you but a 265 bench at your size is below average and a 305 dead lift is also below average.
