The trans counselling charity Spectra (based in London) have a link on their website which then forwards in a few clicks to a Reddit sub reviewing online trans pharmacies and then the site shown in the images below (I don't want to post the full links directly.)
The site asks for payment by bitcoin and is based who knows where selling who knows what unregulated trans drug products.
I don't think that this is posted by mistake by Spectra, I suppose they don't directly post a link to the online pharmacy site but they are very direct in campaigning to provide teens access to puberty blocking hormones; their pronouncements on the subject are very one-sided - they released this statement after the Kiera Bell case calling the judgement 'irresponsible:
At Spectra we are appalled and dismayed that thousands of transgender people are facing difficulty accessing their medication today. A major private healthcare provider has reported that the chemist they partner with will no longer be permitted to fulfil prescriptions, due to regulatory action by the General Pharmaceutical Council...
These irresponsible restrictions, which came into effect without notice, have left people with no access to hormone replacement therapy and other transition-related medications and treatment.
...many people have no alternative but to turn to private healthcare providers for their trans healthcare need, whilst others feel they have no option but to self-medicate...
At Spectra we see the distress this is causing to many trans people and stand with them. The right to exist as transgender and/or non-binary is a fundamental basic human right, as is the right to access healthcare.
