how long you been training for. any experience with gear before.
how tall are you? you should try and get your strength back up before hopping on the sauce. the stronger you are before your cycle, the less muscle you will lose after coming off cycle. you should know that there are no quick results, and thinking like that will lead to irresponsible cycling
If you can't train and eat properly then don't use steroids. What a pitiful attempt... manage your time better. I know students who work full time and go to school and STILL bust their ass in the gym. Start doing full body splits or train DC style. You can do a push/pull/leg routine and blast everything a couple times a week in a short period of time.This, combined with a fuckload of shakes with oatmeal, macadamia nut oil, peanut butter and flax will get you some good mass. If you're not doing the basics right, don't think steroids will fill in the gaps.
