Bsides being able to get it easily, you need to do more research and figure out what else you might need like:
Something for combating progesterone sides like Selegeline or Cabesar. Make sure, like mac173 said, you run Test with it because Deca-Durabolin - nandrolone decanoate - will shut your hpta - hypothalamic-pituitary-testicular axis - down and you will feel like shit. The Test will keep your libido going and help with the bulking as well as overall feeling good(mentally). You'll also need to run an aromatase inhibitor like Aromasin or AIFM. Make sure your diet is clean and you eat 6-7 good meals pewr day(about 4000 cals per day) and you will grow big and strong. I'm sure others will tell you the same thing so I'm not trying to make it sound complicated but I'm telling you like it is.
Good luck.
