Well, I wasn't aware that Superdrug sold testosterone for women. I am happy for you to tell me more, but I thought that anyone using any HRT had to have a consultation with a dr via Superdrug before they could be prescribed it.
They make a living from selling HRT and supplements to women - a GP doesn't.
Gp practices get funding for targets they reach.
You are wrong, sorry, to say private consultants make a living by 'selling' HRT. Most consultant gynaecologists see a wide range of women, from puberty to old age. This includes period problems, endo, infertility, PCOS, prolapse and menopause.
How do you know you are seeing the best? How do you know you are seeing the 'best' GP?
Research. Most have websites, you can study their CVs, see reviews, see if they do research or have written papers etc.
I give them, whereas my GP has my whole medical history at their disposal
But you've just said they can't or won't prescribe testosterone as they don't have the expertise.
