Dbol only 10-15mg daily for 7 weeks was my first cycle, but I was young and reckless really. I did gain about 8lbs and kept all of it with no PCT, but in retrospect I feel like doing orals-only is a waste because your receptors are fresh and you will grow like a weed the first time around. The next cycle I did it right (Sust 500mg/Deca 400/Dbol 25mg)), and I blew up (gained 28 lbs, kept about 19).
If you absolutely hate needles then I'd say go for it, but in reality if you want to do cycles the proper way, you have to pin at some point. Orals over and over are just bad for the liver and you won't make the kind of gains you're looking for.
