I'm 39 and I've been on TRT for about 3 years. My current protocol is 50mg enathate twice a week with the occasional (one month every few months) HCG to prevent my testicles from disappearing. I still don't have morning erections even though my libido is alright. I used to have insomnia i.e. waking up too early and I thought that might be the reason but even after my insomnia improved still no morning wood.
