Yeah on forums people claim that, this is a quote from Provirons Wikipedia page (the source is a book).
"Mesterolone! (Proviron) is not a substrate for aromatase, and so cannot be converted into an estrogen. As such, it has no propensity for producing estrogenic side effects such as gynecomastia and fluid retention. It also has no progestogenic activity.
But if you free up a lot of DHT from SHBG, it’s going to suppress estrogens, so to speak.
Proviron would also have a metabolite that is 1-methyl 3b-diol. But I have no idea how it stands up to 3b-diol.
Yeah my E2 is borderline low last time I checked at 22 pg/mL. I wonder if raising it would help me.
Would you mind sharing your E2 result?
