You're right. Type 1 5-AR conversion happens right inside of follicles, a terrible place for DHT production, and Fin doesn't help with that.
The prob with Duta is that .5mg is the lowest dose you could go, because they're gelcaps, and that's way too much for many guys, inducing sides.
That's because when Dut first came out for prostate enlargement, it was difficult to absorb, so had to be formulated that way.
A newer formulation, with an easier to absorb form of Dutasteride and added absorption enhancers has allowed it to be made in solid tab form, which should be splittable. Available from several India Pharma companies. May be a great alternative to provide even better results than Fin, but at a lower, non side effect inducing dose.
