Hey I'm wondering about the effects of crashing estrogen? My dick still works but definitely not the way it normally works when I'm running test cyp which is what I'm on now. I added in MENT recently and because it aromateses so much more I added in letrozole which is of course very strong. I have noticed no gyno or any other estrogen sides but i may have brought it too low or crashed it due to the low sex drive etc. Maybe I'm doing something else wrong? Any ideas?
