Thats amazing sam!!
I know 1 stone in a few weeks is common but 2 stone is a huge difference even if alot of it is water retention.
Did your friends and family not mention to you that you blew up very quickly?
As for loosing your size with the dbol the answer is yes BUT as i mentioned earlier alot of it is water.
Keep the cals high and train hard and you should keep good muscle mass from this cycle
But all in all impressive gains my friend -well done
