So the internet is full of crap... so I want to have some concrete evidence in here... can someone shed some evidence on this.
I know SERMs lower IGF-1.. but I never use them anyway
Now Arimidex lowers IGF-1, this is pretty common knowledge no?
However I have heard MIXED information regarding Aromasin (examastane) and Femera (letrozole).
Some forums mention one or the other lowers IGF-1 and sometimes that they RAISE IGF-1... can someone please elaborate with evidence?
I know Aromasin is suicidal AI while adex and letro are not... but what about this IGF-1 lowering and raising business?
