My specialist and others say that FAI or free testosterone should be between 2-5%, yours is 0.3 based on those numbers so that’s incredibly low. Mine was 1.4 and I struggled with energy, concentration, memory etc and a little with libido but less of a problem.
The issue with getting a prescription is that there is little research on testosterone and the effects of low levels on women, most research and focus is on men and their libido only. So the NHS may prescribe it to women but with only for low libido and they tend to make you look at other things first. Privately I do purchase testosterone and it probably had more of a positive difference to my life than estrogen but maybe because exercise was a big part of my life that’s more specific to me personally. I do think it’s important, based on what I’ve read, for all of us to have good testosterone levels. You must be struggling with such low levels.
