HCG would help to keep you fertile for sure and if you suffer from atrophy, it will help with that. If you ever wanted to have a baby, you could increase HCG and add clomid. I would use adex year round. Its hard to say how much as everyone is different. Some people need more than others. I would suggest that you get labs done to see where your E level is the adjust your adex dosing from there. You should not need much while on HRT dosing. Maybe start with .5mg 2x wk and go from there
