sus250 (and all tests for that matter) are good because you do not have to add anything to your cycle as far as other A/S.
sus takes about 4-5 weeks to really give you your kick, so some will add dbol in the begining of their cycles to give them a kick start.
some will include other gear towards the end of the cycle to help solidify gains or to help combate bloating. ie winny and fina
but you can do a test only cycle. i would assume this will be your first cycle, so you'll be fine with sus only.
try a 8-10 week cycle. do 750mgs week 1 and 500mgs weeks 2-8/10.
up top you'll see a search button. click on that and type in sus250. you'll get a million hits, you'll just have to sift through them to find what you're looking for.
