If they go by what's in the literature, they will probably dose it way way too high. We're talking 1mg per day because in many published studies on boys that is the dose they use. It's been studied a little bit for pubertal gyno treatment in boys as well as there are one or 2 studies using it in obese men with low testosterone.

Whether or not "anastrozole is the way to go" is a very tough question to answer. It's definitely not the most ideal drug out there, but it's one of the very effective ones at lowering estradiol. I believe eventually it will be replaced in the not too distant future, but with what... I don't know. It's very easy to bring your estradiol into unhealthy low levels and can require months of fine-tuning.

If your estradiol conversion is not super severe, you can experiment with herbal (OTC) remedies including chrysin with piperine/bioperine, grapeseed extract, and DIM. There is limited published research on these combined with some positive anecdotal reports. That's about as good as evidence you will get, unfortunately, for non-patentable supplements because there is no money to be made researching them.
