Hey afg24
I can only tell you what works for me. I am on TRT 200mg/wk test cyp and .5mg every three days of adex and that keeps my E2 around 15-19 thus far. I am almost 2 years in on TRT..Hope this helps you out...I have used HCG a couple of times but it is not a must on TRT...I just use it every once in a while for 2 weeks than come off...
Not sure about your first paragraph, I pin twice a week on trt because I want my bloods to stay stable and it works for me..
