5-alphareductase inhibitor

can anyone help me find a 5alpa reductase inhibitor.well i meant the names of some.thank you

Proscar, Propecia (Finasteride)

dutasteride (Avodart)

don’t think this one is available in the US yet


Avodart is currently available in the U.S. (I did a sample-size trial of the stuff for BPH.)

What is the allure of this stuff? I mean, what is the appeal to the t-mag world? I’m assuming it isn’t for it’s use as treatment of BPH.


Avodart (dutasteride)is an inhibitor of both type 1 and 2 5-AR, while finasteride is mainly type 2. Type 1 has the greater effect on the hair follicle, type 2 on the prostate.

Remember, some of the effects of testosterone are dependant upon its conversion to DHT.

I’ve been using Avodart for almost a year now and my DHT levels are sub-normal. I’m actually cutting back my dosage to get into a mid normal range

Keeps the prostate in-check when on a cycle. also, its suppose to protect the hair line, but it really hasn’t worked in my case. However, I piss like a 10 year old boy!
