Saw Palmetto is an ANTI-ANDROGEN, it will lower DHT somewhat, along with your testosterone! Why people continue to take this shit is beyond me, but oh well, some peole like flushing their money down the toilet...
It doesn't lower DHT, nor testosterone. Don't confuse the facts. It's been shown to exert tissue specific DHT reduction, by blocking 5AR, at the prostate, as it's been shown in the studies that show no reduction in serum DHT with SP usage. On the other hand it doesn't "lower testosterone" ... it binds to the prostate androgen receptor, thus competing with other androgens, be it testosterone, DHT, primobolan, boldenone, 1-test ,.... whatever.
Saw palmetto has a very wide array of mechanisms by which it benefits the prostate. Some of them:
1) Prostate SPECIFIC blocking of both 5AR type 1 and type 2. This is, I think, one of the reasons that people trying to stop hairloss using it fail.
2) It binds to the androgen receptor in the prostate. Whether or not it also binds to skeletal muscle AR remains unknown. Even if it did, and hinder gains somewhat, given the fact that it benefits the prostate from many angles, I think that, in proportion, you get much more prostate prevention than hindering of gains.
3) It blocks Alpha 1 Adrenoreceptors.
4) It has anti-estrogenic properties in the prostate.
As you can see, Saw Palmetto is a lot more than "shit".
