From the Mail article linked by IstanbulConstan about children buying puberty blockers and cross-sex hormones online.
Mermaids, a charity supporting transgender children, said the drugs ‘can subject a young person to distressing bodily changes that can lead to an increased risk of anxiety, depression, self-harm and suicidal ideas’.
That's a new line for Mermaids to take. Unless they've been misquoted, in which case it would be difficult for them to correct it without it looking as though they support children buying these drugs online.
Also a quote from the Tavistock mentioning detransition.
‘It is incredibly dangerous to buy these online,’ said the spokesperson, who pointed out that many young people later change their mind about changing sex. ‘By getting drugs off the internet, adolescents may start on a path they don’t want to tread later on.’
