yeah i been told that if u passed puberty then u cant have it but it more for people who are young like age 13 or so, but im not sure if it true, if it was i wish i kinda known about it and had it then but im way pass on my puberty now.
Also i read somewhere that if someone is taking alot of T they take the blockers to stop it from turning into E, so yeah i dont really know alot about it either, only just heard about it and read it somewhere online and im a little confused.
