I'm not familiar with that medicine but from what I read, that does seem like a high dose. When I was on testosterone, I had it compounded (I'm in the US) because the preparations here were all for men so it would be a challenge for me to get the right dose. With the compound, I still started on half the dose they said and built up to the regular dose. It took a few weeks but I really could tell when it kicked in. After that I honestly adjusted the dose based on how I was feeling. Sometimes it was half a click, sometimes 2 full clicks (how the dispenser was). I never got a deeper voice or grew hair on my face so it worked for me.
Maybe someone who has used this in particular can be more helpful.
