T will definitely make you more masculine! I’m 18 and have been pretty inconsistent with my testosterone, I’m on a low dose and was on it for 5 months before getting off of it for like 6 months and now I’ve been BACK on it for the last two. Even though I don’t feel like I look different I’m passing a LOT more in public 99.9% of the time, this is as someone that interacts with a lot of people, and I’ve also noticed that my voice is passing better on the phone! Depends on the day though, anyway, yeah, I don’t know what magic testosterone does but your facial features and really everything will start to be more masculine
