Five years on HRT to "start commenting" is exaggerated and way too pessimistic, if you ask me. Before this thread, every testimony I have read, without exception, stated even though, often, nothing obvious came for months, within the first 2-5 weeks, there was always something. Maybe I always fell on the wrong reports, but even if I did, I think the data I have is enough to rationally suggest that SOME change is normal to expect after a few weeks.
E's effects are quite slow, but an anti-androgen, at an appropriate dose, usually does at least something in a few weeks. I mean, when they use them to chemically castrate criminals, I think they only wait for 3 months to check.
