Blocking dht for recessive hairline? is this safe? will excess testosterone be converted to estrogen instead of dht if i do this? could cause gyno??

5ARIs block DHT: You've been studying! That's awesome! Seriously! As you noted, 5ARIs (alpha reductase inhibitors) block conversion of Testosterone into Dihydrotestosterone. However, as a consequence, you might convert T into Estradiol (estrogen). This is a real concern w/side effects such as gynecomastia, loss of libido, erectile dysfunction listed in small print for drug. Only u can decide if benefit worth risk.
