I think I may be a special case, but I had a full mustache before T, and a decent amount of hair on my chin, though nothing that could pass as a male beard. It was only a month on T before I had sideburns, and by 2-3 months I could grow a full beard. The body hair has come in a little more slowly, but I'm now over 3 years on T and have plentiful hair on my chest, stomach, back... you name it, I've got it. My dad isn't hairy in the least, but my little brother (he's 21) and I now have identical body hair patterns.
