this is true, testosterone isn't just about the amount and presence, the timing is extremely important too and taking it once you're a fully finished with growing adult testosterone's ability to virilize is severely reduced.
masculinization happens in stages starting from when you're in the womb, missing out or having a deficiency/insensitivity at any stage permanently locks you out of a degree of virilization the same as other males who develop normally
it's why 5ARD males can't compete with males in sports, they're always a significant step behind because they missed out on a crucial shot of DHT in the womb that every normal boy gets, it fucked up their dicks and ability to be as athletic as other men. they're stronger/faster etc than women but weaker/slower than other men
