You are welcome. Labs can be a dangerous thing, especially blood only labs. They only show a snapshot of a moment in time. They don’t show metabolism of the hormones into downstream metabolites or which pathways are being used etc. this is extremely important info. I have some patients who feel their best at 600 and some who feel amazing at 1400. It just depends and there are loads of factors but never once has an e2 range been locked in for us.
