I guess ill be the one to bite.
How do you consider this good news? All scientific literature indicates that prescribing puberty blockers to trans youth has a large benefit to the state of their current and future mental health, while also causing no harm as once they stop taking them, if they dont further transition, their regular puberty takes over with no decrease in how much they mentally and physically develop (dont forget, these are also regularly prescribed to cis kids too)
What the other user said is correct. Generally puberty blocks are limited to use during adolescence, with use being discontinued in the very early 20’s at the latest. They are a measure to buy time for a person to meet an age of greater maturity so they can make the decision to further transition medically or hormonally. They are not intended to remove sex hormones from the body forever (much to my personal dismay)
