Certain steroids are 17-alpha alkylated which allows them to be taken orally and not destroyed by the liver. Steroids like winstrol, anavar, dbol, tbol, anadrol etc.
The thing that sucks about those oral steroids is that the same 17-alpha alkylated structure that allows them to be taken orally also makes them liver toxic. You are going to want to use a good liver aid supplement like n2guard from n2bm.com when using them to keep liver toxicity to a minimum.
Here is a video where I explain how to properly run an oral only bulking or cutting cycle ->

A cutting cycle might look something like this -
Weeks 1 - 8
Winstrol 50mg/day
Anavar 50mg/day
A good natural liver aid supplement like N2guard - 1 serving/day
A good natural testosterone booster like HCGenerate - 1 serving/day
A bulking cycle might look something like this -
Dbol or Tbol 50mg/day
Aromasin 10mg every other day or arimidex 0.5mg every other day
A good natural liver aid supplement like N2guard - 1 serving/day
A good natural testosterone booster like HCGenerate - 1 serving/day
After both cycles, it's important to run a proper mini PCT.
4 weeks of the following:
clomid at 25mg/day
nolvadex at 20mg/day
A good natural liver aid supplement like N2guard - 1 serving/day
A good natural testosterone booster like HCGenerate ES - 1 serving/day
