I've been on TRT for a little over four months now and my previous endocrinologist had me on 200mg 1ml (ethanate) every three weeks and I complained about a heavy crash only six days after my injection that felt like a rollercoaster, I do understand the injection interval is a problem since it causes me to crash. I saw my new primary doctor earlier this week and had extensive blood work done and my testosterone was 600, E2 at 50.0 right at the upper limit, all others were spot on, yet I felt like I was crashing four days before the blood work? Up until I start crashing I really felt fantastic with incremental improvements every day, day six I cleary start feeling horrible again, even worse than before I started TRT. How is it that I feel horrible with my test at 600? Test was 1195 seven days prior and I see my new Endo on the 18th.
