Well you didn't really ask any questions.....
Based on your weight/height/bodyfat ... and assuming that you are measuring correctly....yeah you can expect to gain up to 30lbs if you run a long cycle with everything in check.
I don't know what to say besides that
i would rather run test prop since you are already very lean. Already being lean and staying lean on an aggressive cycle is a good feeling.
You didn't really ask about dosage but I tend to recommend a good amount more test than most people on test-driven cycles. I also suggest longer cycles to new people.... just my thing. 600mg/week of prop ballpark should do a lot

. I would suggest more if you weighed more and were taller.
