Ive been on trt since last June my protocol is sustanon 250mg every 10 days. For about the first 5 months my libido and erections started to improve but i felt fluctuations. Some days my libido and erections were zero and some days really good. But since last November i havent had even a single day when my erections and libido would have been good. I checked my testosterone and it was good 21 nmol 7 days after injection. Ive measured my e2 twice it was 0.13nmol (36pg) 6 days after injection and 0.15nmol (40pg) 12 days after injection. Not super high but could the e2 still be causing this? My shbg was 15nmol. Ive also developed a bacne during this time and had loss of penile sensation
