1 amp of sust per 10 days is little more than a test replacement therapy dose. the 6 weeks of anadrol will do a nice job blowing you up with temporary water gain, and great strength, while tearing your liver up nicely.
i take it that this is your first cycle, and as a first cycle, i wouldn't use anadrol. hell, i wouldn't use any alkylated drugs. you can get plenty of gains from other AS. alkylated drugs are overated in my opinion. i've been through 4 cycles, and the last two were only test cycles, and were the most successful permanent ones. the first ones i fucked with winny, dbol, etc, and it was just a big fucking waste of time in my opinion. the gains in strength were temporary. so while not getting much results, i probably managed to plaque up my arteries a bit. so, if i could do it again, i'd never touch orals. they're cause horrible athleroschlerosis.
if i were you, and all you have is sust, then take a 1000 mg the first week, 750 the second, and 500/week for 6 weeks after that. just do a test cycle. you'll make great gains off of that, and you won't fuck your lipid profile up as much.
