I didn’t have a major issue with libido, mildly different but the main issues I was prescribed it for was energy, brain fog, lack of concentration, memory issues, focus, things like that. All have improved or gone. I have noticed quite big changes in my body adding it, easier to build muscle now and less fat because of it, less cellulite things like that. I exercise almost every day and grow my own food so am active a lot whereas at times before HRT I could barely get up and certainly hardly exercise at all, which was important to me before all this- I was an endurance person, lots of distance sports etc I don’t think testosterone has given me any issues. Utrogestan & estrogen were harder to get used to and get the right dose of and I definitely had side effects from those which have mostly eased 9 months in. Good luck with it all
