chances it is not - as for males this is usually the first place
you put it on.... maybe a little is but soulds like you made some
good solid gains.
I'm in the process of some seroius bulking now - aiming for about
130kg but keeping the bodyfat in check - I feel gaining lean is the
best way to go over the traditional "bulk up" where you pack on a
ton of fat.... people forget the pros that do this use drugs and
can gain a lot of weight very quickly and can cut the fat even
quicker - if you are natural you can't get away with that.
