I have been on testosterone 1% for 3 months now. I feel like it took 6 weeks or so for me to feel the effects. I'm happy to say that my libido has increased, not to the same levels that it was before, but I'm hopeful that it may continue to change. My doctor says that it takes about 6 months for things to level out in your system.
I was completely averse to sex for the last 2 years and now I can actually initiate sex which is huge for me.
I haven't noticed any other changes that you get warned about.
If anyone has any questions please feel free to ask. And I would urge anyone who's having libido issues to inquire about going on testosterone because estrogen did nothing for me in that regard.
We always hear about voice deepening, more facial hair, or hair loss, which I think scares people off, but have you noticed anything different with muscle mass (like maintaining what you have, or building more)? Or feeling more energized?
