Imo there are a few mental changes.
People might get more emotional, intuitive, willing to make conversation and even get more creative.
Well many endos strive for testo values of below 60 ng/dl. There is a fine tuning possible, so values do not drop to zero.
Testo levels being not too low might have an influence on activity.
Well if estrogen levels are well in the female range, many endos strive for values of above 200 pg/ml, it might be possible you feel well .. and energized...
levels in the menopausal range might be quite low ... trans women are not menopausal women ...
concerning senses many people report a heightened sense of smell, and some a change in sight ... being able to see some colours better ...
many people regardless of age said they lost some height , maybe one inch, and their feet became smaller one or two shoe sizes ... there are threads on it, you can look it up.
There is more to height than just bones ... there is cartiladge in between, and there are muscles responsible for gait ...
well if you are unsure you might want to start out with a low dose.
I'd say talk with your endo about all of this.
Many people report a feeling of relief, it might be the same for you. Its like their brain expected this.
