I've done a bit of reading as well. Stopped after reading about vision issues, although that could be dose related and not an issues for HRT level doses. Being suppressive probably isn't a concern for HRT. You're should already be suppressed if you need HRT.
I think I will probably leave them alone until there's a lot more data. Just seems safer to replace exactly what's missing. Using and AI and HCG for decades might be a bit of a concern, but it seems like standard protocols are a bit more 'natural'.
