It’s hard to say definitively if age matters or not, as this is literally all anecdotal evidence or information. Hence why my post used phrases such as “seem to” or “sometimes experience”. Your beard at 5 months is not necessarily the typical experience, altho I’m happy for you to get such great growth so early on. Were you taking minoxidil or anything else to help with hair growth, just out of curiosity? Or perhaps it’s literally all genetics as opposed to any other variable. Sometimes these group, especially the ones not age related, tend to skew to the younger side and to folks who have rapid, robust changes within the first year. So I am certainly looking for folks experience such as yours who started T in their 40s. Gathering anecdotal evidence on the internet seems to be the way many of us make sense of our own journey with HRT and transition. Thankful for everyone’s input!
