Experts on background and overview · 5 cited mentions
"Now in the hair loss prevention community, it seems that dutasteride is a little bit more favored than finasteride. A part of that is due to the half-life or maybe it's just a little bit better efficacious compared to finasteride on a milligram per milligram basis."
"test a TRT dose topical dutestaster topical minoxidil topical RU 58841... I wouldn't take oral dutestra"
"In terms of selectivity of I think it's type two 5-alpha reductase. Yes, the research shows that it's a little more favorable towards blocking the enzyme that affects hair follicles."
