Should be from the VN Shuffel <| sep |> Not a clue for your second question but regarding the first . At 24 you went through all the growth plates finishing up . The brain is supposed to finish growing around 25 so you might already be there . The only thing that likely will keep coming for another 5 or so years would be facial hair as long you have the T . Male pattern balding in your hairline keeps happening under T . And your face will still become slightly more angular over the decades . Which is why older men sometimes look more masculine than they did in their early twenties . Just keep in mind that if you get an orchie you will still need to take E or T supplements in order to prevent brittle bones .
