I agree with Pat Arnold for the most part. DHT shouldn't be classified as good or bad in and of itself. I also agree that finasteride does not need to be used by everyone, only those susceptible to androgen related hairloss. Unfortunately, I am afflicted with MPB and therefore I take finasteride everyday. I noticed a small decrease in libido when I first started taking it a couple of years ago, but I can live with it. However, I recently linked a decrease in strength with my use of propecia. I had known about DHT's effect on the CNS for quite sometime but it took me awhile to put two and two together. So what Pat says is true...at least for me. I constantly feel overtrained and my recovery is slow even while on cycle. But I have to accept these drawbacks at this point to try and keep some hair on my head. It is a necessary evil I guess. But enough about me...heheh.
What I found interesting in the article was his statement about DHT's effect on the production of gonadotropins. Perhaps finasteride could be added post cycle in conjunction with clomid/arimidex to aid in kickstarting natural test production.
