It is known guys who haven't responded to finasteride have jumped ship to dutas and have had results. Is it at all possible that someone may respond to propecia and not (or not as well) to dutas? I know that dutas (at a .5mg dose) is blocking 98% in the follicle and finasteride (at 1mg) is blocking around 85% but I was wondering if anything else could contribute to finasteride being better for some people than dutas? any input?

Google it man :)

Basically, pharmacogenetics refers to how one's genetics can influence the way a given medication works in an individual. For some people, because of their genetics, Finasteride works better then Dutasteride despite dutasteride being more potent.

Like for me, Advil (pain med) does nothing for me if I have a headache where as Tylenol knocks it right out... For my mom it is the opposite.

Thanks socks, but i believe you're comparing apples to oranges here. Advil and Tylenol work to alleviate headaches in completely different way. advil works by reducing hormones that cause inflammation and pain in the body, where as tylenol works by elevating your body's overall pain threshold. They are attacking the head ache in completely different ways, where one way might be more effective than another. Where as with male pattern baldness both dutas and finas work by REDUCING DHT via 5ar inhibition. Anyone else with any input? maybe bryan or michael barry?

I was discussing dutasteride offline with Michael Barry and it sounded like he was looking for more long term study info about dutasteride before he would personally use it.

I think you missed my point hair today gone tomorrow!!!

Advil/Tylenol works for one person but not for another person because people's bodys work a little different from one another. This is referred to as pharmacogenetics. Again, for me Advil does nothing where for other people it does. For me Tylenol works where for other people it does not. Now I understand you cannot compare Advil/Tylenol to finasteride/dutasteride in the context of both drugs having a similar way of working but that isnt the point. The point is, different drugs affect people differently and even though finasteride/dutasteride work on the 5ar enzyme, they are totally different drugs.


You asked if there was something that could contribute to finasteride being better then dutasteride for some people and I answered your question. Instead of asking someone to spoon feed you every detail why dont you look into the subject of pharmacogenetics? I'm sure you will find atleast one possible explanation to your question.


Good luck!

Im not asking to be spoon fed...Im simply asking if anyone has responded better to finasteride than to dutasteride...I dont think Im gonna find that on google. I do thank you for your response though...It seems as though no one else has any idea/opinion.

BTW socks, I know youve been on oral spironolactone + finasteride for awhile and now you are just takin 5mg of finasteride E.O.D. What is your opinion on dutasteride?

I wouldn't mind hearing more from those who have switched from finasteride to dutasteride or vice-versa.

what were your dosages, levels of success, and reasons for switching?

how are you doing now since the switch?

Peace Out!

Dutasteride looks good on paper and without a doubt works well for many men... I certainly would not discount Dutasteride as a possible treatment. However:

I think every guy should try Finasteride first and give it a fair 1 - 2 yrs before considering Dutasteride. The reason?

1 - Cost. Finasteride is dirt cheap.

2- Finasteride is effective in the vast majority of men. There is not a need to jump to dutasteride if finasteride is going to do the job right?

3- The main cause for hairloss in genetically predisposed individuals is DHT produced via the Type II 5ar in the hair follicle cell itself. The Type I 5ar plays little to no role in male pattern baldness as demonstrated in pseudohermaphrodites (men born with the inability to produce the Type II 5ar but can produce the Type I 5ar) who never go bald as well as the studies done by Merck with MK386 (a Type I 5ar inhibitor that showed no or little effect on male pattern baldness).

The main reason dutasteride is more effective then finasteride is because it inhibits more Type II 5ar then 1mg of Finasteride. The inhibition of the Type I 5ar simple makes side-effects more probable as well as causing a higher upregulation of Testosterone (finasteride does too but not as much as dutasteride). Testosterone, like DHT, is an androgen and can contribute to hairloss just the same as DHT (though to less of an extend since it isnt as 'potent'). I personally think the reason why some men get frontal recession on dutasteride is because of this testosterone upregulation.

Lastly, DHT is not just some stupid hormone that does nothing but cause hairloss. IMO, it makes no sense to reduce DHT anymore then you absolutely -have- to. Again, if finasteride can do the job use finasteride.


So in summary, Dutasteride is a good drug and it works well for some men where Finasteride may not (perhaps due to pharmacogenetics or perhaps due to over-sensitivity to androgens like DHT). It is more expensive however, inhibits more DHT overall then is really needed, has a very long half-life once you build up a steady state of the drug into your system, and causes a higher degree of Testosterone upregulation.

Personally, Dutasteride has always been my last resort drug. I would personally sooner use finasteride and spironolactone over dutasteride... But that is just me. I have wrote a lot on this subject and this really is just a brief summary... But that's the 'just' of it.

How much dutasteride are you taking and how frequently (I'm just assuming you're using dutasteride btw)?

Don't mean to hijack this or bring this off-topic, just wanted to highlight this little tidbit you mentioned above for a few other people on this board! :)
