What height are you at 160lbs?
I highly suggest you train another 6-8 months naturally, at least. People who have just started training are at the greatest risk for dropping gains really fast after steroids. I know it seems like the "fast track" to getting ripped, but it isn't.
With any steroid, the body will lose some after the cycle is finished. We have ways of trying to minimize it, but none are perfect. There will be periods where your body has no natural testosterone production.
Adrol is not a good choice if you want to keep your abs. It will put mass on, but cause bloating.
Steroids are also not very useful unless you are eating like a protein-hungry, calorie-counting pig. What are your calorie counts and diet like?
What training routine are you following?
