1. Dutasteride, at 2.5mgs/day is roughly 1.5X more effective than finasteride at 5mgs/day, at treating hair loss (both halting it as well as regrowing it).
In addition, dutasteride can be used successfully at that same dose to treat prostate enlargement, and a lesser known effect of dutasteride (again, at that same dose) use is to treat acne caused by an overabundance of androgens in the body.
2. For the steroid using athlete suffering from dht-related side effects, dutasteride may be the answer. Hairloss, acne, and prostate growth can all (potentially) be completely halted with the use of this product. Unfortunately, dht is not all bad, and you potentially lose some muscle hardness (an amorphous quality if ever there is one), and even some of the other qualities we like from our androgen use.
