Tibolone is well tolerated and very effective, there aren't many studies because it's banned in the USA. It's banned as it can help young healthy athletes cheat in their games, which is more important than the millions of women in America who have progesterone intolerance and menopause together every year.

I hope the UK doesn't jump on that misogynistic bandwagon because after telling the GP I was intolerant to progesterone, I was told that doesn't happen in menopause, then had to trial several suicide inducing progestins before I was allowed tibolone, it's disgraceful, but it's only women suffering, so who knows what they'll do.
I need my tibolone to feel good, also I know it's helping my bones, possibly every organ is benefitting and
until they produce an alternative I hope they don't disregard us as a bunch of older women, safe to ignore.
