No it doesn’t. It’s part of the drug itself to lower Testosterone and increase shbg, it’s meant for prostate not hair. And the mechanism remains the same, it’s only dosage that changed with “Propecia”. Estradiol usually remains the same, I’ve had blood tests done during taking Finasteride and e2 was not elevated, in fact it was slightly reduced. You know why? Because T levels started to drop. It’s not the “elevation” that happens, it’s the “ratio”. Also, if you take thyroxine and try to take finasteride too, your tsh will plummet. Crazy right? Well, finasteride does many wondiferous things.
Dude where have you been reading ..
The change in T is because less T is converting to DHT so there is more available, which also gives rise to an increase in E because there is more T to convert depending on how much aromatase your body produces.
Every independent study has shown with finasteride a rough average increase of 10% for both T and E. SHBG in the main remains unchanged, although there is some literature suggesting that DHT aids in keeping SHBG down but I’d imagine that would be more of a problem with dutasteride (potentially)
