I have a lot of my father's characteristics--hairline, cheekbones, ears, overall facial structure--and his body type. Not to mention his bushy eyebrows, although my barber likes to trim them to keep them from getting too unruly.
Before T, I already had all of these characteristics except the eyebrows and the hairline.
After five years on T, I think I look quite a lot more like my father, but I really just look like a male version of my former self.
I think that T will enhance those characteristics that you already share with your father, but if you don't look that much like him now, I wouldn't expect you to suddenly transform into him just because of the T! But I suppose the only way to be sure is to go on T. Is looking like your father a deal-breaker?
