Hey, I have used Lenzetto 3 sprays with 12.5mg of CPA every day for around six months, as per the indication of the endocrinologist. The 3 pumps are usually not enough for proper feminization. Estradiol levels with Lenzetto fluctuated a lot and usually stayed below 100pg/mL (<365pmol/l). It is the only treatment that is given officially in our territory, so after talking to some other transfems in my area and looking at their analysis, they all had the same problem. Some were even taking 4 pumps without much better results. Lenzetto is just not very strong as an estradiol delivery mechanism, some of us went DIY after realizing that. Antiandrogen seems to be working fine although like it has been pointed out it's still pretty high.
