It does not show the study but makes refrence to it.
A leading TRT doctor here in the states suggests that men with alot of aromitization should use soy and flax in their diet to control estrogen.
But he recommends that men with low belly fat to avoid flax and soy.
There are many natural aromatase inhibitors that will lower estrogen like. chrysin, dessicated liver, tobacco, Diindolylmethane (DIM), cruciferous vegetables, Indole-3-carbinol (I3C) as examples and all are over the counter and do work.
So again if Rob is natural he has access to these during contest prep.
That would be kind of interesting.
I may add some flax to my diet just for GP
