Hi all. I am a 53 yom who has been on TRT for roughly 13 years. I seem to have an issue with my libido coming and going in a somewhat predictable cycle. Typically I'll experience raging libido for maybe a week to 10 days, and then it'll drop off to the point where I can't get an erection even with PDE5 inhibitors. Usually the inability to get hard at all will only last a day, maybe two, and then the libido slowly seems to recover over time. It's almost as if when my libido is high, I can fuck until I wear my dick out and then it wont work for a day or two. The depressed libido though will last for maybe 3-5 weeks. I can get hard and have sex during this time, but it's nowhere near as satisfying and the erections are hit and miss. It seems similar to a hormonal cycle in women.
I'm guessing the smart approach would be to do bloodwork both when my libidio is high and then again when it's low, but I've not yet done that. My doc has me on 400 mg of test cyp 2x / week, and adex 3 x / week. That seems like a boatload of test but I've been doing that dose for a very long time and this is the only issue that I've had.
Just wondering if anyone else has experienced anything similar. Thanks!
