I'm not on T yet, neither i'm experient with those things, but... Seems like the voice dropps quickly, compared to the others "symptoms". As for quickly, i would say 4 months. But it surely is something that changes from person to person. Don't worry, maybe the day is closer than you think =)
The facial hair, aparently, only grows completely after 3 years on T, more or less. Of course it can comes before, again, it's something that depends on your genetics ^..^;
