Apart from possible sides, is there any REAL reason to start with fin over dut?

Even if you did I could refute that with twice that number of men reporting sexual sides, decrease or loss or libido and erection dysfunction simply from the fact that Dutasteride is far more powerful as DHT Inhibitor than its cousin Finasteride before it.

Yes, the side effects are at least 50% more frequent. 2% vs 3%. A huge difference.

Stop this fearmongering, please. Both finasteride and dutasteride are very safe drugs. Well, we can't be so much certain about dutasteride yet, but the stopping of hairloss doesn't require a complete eradication of DHT.
