Something is off here. Maybe his source was supplying him with fakes? I'd suggest going through Naps, and using Geneza Methan. Some of the very best dbol I have ever used. I used to use Naposim all the time, but heres the way I see it. If I go through Naps for GP brand gear, I can be certain that I am getting legit GP gear and it's always great. Naps has lots of good brands, but GP is what I know best so it's what I suggest to others.
Another possibility is that he wasn't eating enough to grow. I would still expect that he gained a few lbs of water, but remember that steroids alone are not going to do much. It all comes down to diet and training, in order to get results...lots of hard work, but hey, if it was easy, everyone would be huge and ripped!
