I had hair on my chin and upper lip before T, and when I went on T, that hair got thicker, though what I noticed coming in first was sideburns, probably about a month in. My facial hair really seemed to grow out from my chin, so while I had a decent bit of neck hair, it was mostly toward my chin. I've been able to grow a good beard since about 2 months on T, but it's only recently started filling in completely between the soul patch and chin... just goes to show that T keeps working its magic well past the first few months. I've been on about 17 months now, and it's going well.
