Well, I do not know what to think. I googled "muscles and Finasteride" and I heard both versions of the story.
Specifically, on a website a guy that works out said that while on propecia he lost power and muscles. He said he went to get his blood checked and his testosterone was low. The guy, for the record, was 44.
However, here's the opposite story. A bodybuilder guy wrote a long article on how to maximize the effects of steroids.
His number one suggestion was to get on Finasteride, since DHT is a bi-product of Testosterone. He says that you do not want Testosterone to be wasted into DHT, since it is useless for muscle. He said that you want to keep as much testosterone as possible in the body to maximize muscle growth.
Another hint in favour of finasteride and muscle is that there's a very popular bodybulding supplement that guarantees maximum testosterone boost by avoiding the conversion into DHT.
They say that DHT is what you do not want when building muscles. They aslo say it is not good for sex (?) Among their ingredients I saw Saw Palmetto....so I guess that that's what they use...but forget about whether saw palmetto is effective or not, what is important is their theory.
Now, it all kind of make sense in a way. I read many times that DHT is super important for us when we grow and develop into men. After that, we do not really need it as much, since we are already developed, and the theory is that since it is unused by the time we get older, it starts to accumulate in the prostate and the scalp, causing damage to the hair.
Now, we must remember that when testosterone does not convert into DHT, it stays in the body in a "extra" amount, some say as much as 15%.
This extra amount is supposedly what bodybuilders look for.
Most importantly, it MUST be stated that I heard of many situations in which people actually get hornier while on finasteride, as a result of the extra testosterone floating in the body.
However, some people claim that DHT is super important for sexual activity...
I do not know what to believe....but I always heard that to have muscles and to have sexual energy you need testosterone, I never heard of DHT before knowing about finasteride.
So I don't know....
