I think an issue here is the imprecise wording (and sometimes indecipherable spelling) of your posts, which often make it hard to figure out exactly what you are saying and what info you're asking for. Such as this statement of yours a couple of posts up:

Detransition Is vanishingly rare and noting irreversible is dibd before adolescence and I have never seen gc cite any statistics on adolescent desistance

When you say you've "never seen GC cite any statistics on adolescent desistance," do you mean stats regarding persons who had childhood GD (onset well before puberty) and who desisted during adolescence? Or do you mean persons who developed GD during or just prior to adolescence, and who desisted at a later stage of adolescence?

I believe GC has provided many sources showing that the vast majority of kids with childhood GD desist during the course of adolescence.

But it might be that you and other posters here are using the word "adolescent" to mean different things. Could you say what you mean exactly so to eliminate further confusion?

Finally, is "dibd" a typo or an acronym for some new gender term? Genuine question- it's not clear to me.

You say that

Hormones aren’t being introduced until mid to late teens at the earliest.

Again, please state what you mean by "mid to late teens." There are 7 different, long years between 13 and 19; it's best to be specific.

My impression is that you think adolescence = teens, or is roughly equivalent to the teenage years. When, in fact, adolescence usually starts well before the teen years. Puberty is only precocious if it starts before 8 in girls, and before 9 in boys. Most girls start developing breasts and begin menstruating well before they turn 13, often several years before. Similarly, most boys begin experiencing wet dreams and genital changes and growth, and engage in masturbation resulting in orgasm, well before they turn 13 too.

If my impression that you're conflating being an adolescent with being a teen is incorrect, I apologize ahead of time.

Another issue adding to the confusion here is that is that puberty/adolescence unfolds very differently in children depending on sex - and thus boys and girls of the exact same age are often at very different stages of adolescence. Not only do different processes occur in female and male bodies during puberty and the rest of adolescence , but these phases of development occur at a different pace in the two sexes, and where common events occur - such as the growth spurt that leads to adult height, adult shape and increased bone density - the sequence is different depending on children's sex. For example, girls go through our big skeletal growth spurt at the beginning-middle of puberty and usually achieve our adult height by 14, whereas boys do so towards the end of puberty or even during adolescence after puberty is over, achieving their adult height at or after 16. Though this varies in individuals. For example, I reached my adult height at 12, but my brother didn't reach his until 17.

But however you personally define what you mean when you speak of "the mid-late teens" and "adolescents," it remains the case that your claim that "Hormones aren’t being introduced until mid to late teens at the earliest," is simply not true. Nowadays, and for a number of years now, kids with gender dysphoria are indeed being placed on "hormones" in their early teens, and some before their teens even start.

A paper published in 2019 by Johanna Olson-Kennedy MD et al reported on a study funded by USA's NIH that began in 2016 that attempted to assess the impact of early medical interventions on "transgender youth." It says:

Regarding age, the minimum age in the inclusion criteria for the gender-affirming hormone cohort was decreased from 13 years (as stated in the original grant proposal) to 8 years in order to ensure that potential participants who might be eligible for hormones based on their Tanner stage would not be excluded due to age alone. Additionally, considerations were made for youth who were found to have very low bone density in the screening, which occurs with youths initiating blockers. Only 7 youths under the age of 13 years at the time of enrollment were enrolled into the cross-sex hormone cohort.[ "only 7" - WTF?]

Another study published in 2018 by Olson-Kennedy et al of 59 patients who presented for treatment at a youth gender clinic from 2011-13 and received "hormone therapy" states that the youths

ranged in age from 12 to 23 years at initiation of [exogenous estrogen or testosterone] therapy, with a mean age of 18 years. Thirteen (22%) youth started [cross-sex] hormones younger than age 16 years.

Transfeminine youth were started on hormone protocols that usually included a testosterone blocking agent and feminizing medications. Spironolactone (100–200 mg orally per day) or a GnRH analog was used for testosterone blocking and induction of feminizing features with 17 β estradiol, and in some cases, the addition of progesterone. At the time of this study, spironolactone and GnRH analogs were not covered by most insurance plans; therefore, seven (28%) of these youth did not have their endogenous testosterone blocked specifically in the first two years of treatment. One transfeminine young person was on GnRH analogs since early puberty. Eighteen participants used an escalating dose of oral estradiol ranging from 1 to 6 mg each day; four switched to injectable estradiol over the course of treatment, and one was off of hormones at the follow-up visit. Six participants initially started, and continued using injectable estradiol at doses ranging from 20 to 30 mg delivered intramuscularly every 14 days.

Transmasculine youth were all treated with testosterone cypionate via subcutaneous delivery at escalating doses ranging from 12.5 mg to 75 mg weekly. At follow-up, most youth were at a dose of 50–75 mg weekly. Two transmasculine youth were on simultaneous GnRH analogs that were started earlier in adolescence. Doses for both cohorts were adjusted based on clinical response and circulating levels of sex steroids.

Jazz Jennings started both "puberty blockers" and exogenous estrogen when Jazz was 11. Since Jazz turns 21 in a few days, that was a decade ago.

Jackie Green of the UK, child of Mermaids' CEO Susie Green, started both "puberty blockers" and exogenous estrogen at 12. Jackie is now 30, so that was 18 years ago, in 2003.

Helen Webberley the UK physician who operates Gender GP, an unlicensed online clinic, has been prescribing cross-sex hormones to children as young as 12 for at least several years now. This first came out in the investigations in 2018 that followed the suicide of one of Webberley's teenage female patients for whom Webberley prescribed testosterone, and more info about other patients has come out in the formal proceedings against Webberley by medical licensing authorities that have been held over the past couple of months.

Trinity Neal, the first child in the US state of Delaware to undergo "childhood gender transition" paid for by Medicaid, started exogenous estrogen in 2016 when Trinity was 13 and at 16 became "one of the youngest people" to undergo surgery to remove Trinity's testicles and reconfigure Trinity's genitals in "gender affirming" fashion.

Speaking of surgery, an intervention that is not reversible, another study by Olson-Kennedy et al published in 2018 showed that girls in the US as young as 13 are being given double mastectomies for gender dysphoria. In the sample studied, 49% of those who had double mastectomy for GD and "chest dysphoria" were younger than 18 years at the time their breasts were removed.
