@forevershallon cross-sex hormones literally cause a second (or first) puberty, but okay. kids on PBs can come off them at 17 and still go through puberty. it is extremely rare that they'll still be on them post-18. it's a temporary measure
@stillcantbgigi the point of PBs is to TEMPORARILY stop puberty until the person feels comfortable enough, they are rarely used in the long-term as you are suggesting. as soon as they get off them, their bodies will develop as normal. it has zero effect on their brains, it simply pauses puberty
