When I first started using herbal NBE, I was taking primarily FG and SP. I definitely put on weight during that period, which I am only now beginning to get a real handle on a year later. I started reading about PM 3 months or so after starting on FG and SP. I did not notice any appreciable effect on erections or libido while taking FG and SP.
I switched over to PM primarily because the evidence suggests FG is mostly a galactogogue and would not increase breast growth. I kept taking the SP for another couple months along with PM. I stopped taking the SP but kept taking PM. I did notice appreciable effects on spontaneous erections, morning erections and a very marked decrease in libido after taking PM for a month or so. I noticed no change what so ever after stopping SP. Based on my experience I question the effectiveness of SP as an antiandrogen.
In fact, it's effectiveness at reducing the symptoms of BPH are very much in question by the most recent research. (
http://www.cancer.org/Treatment/Treatmen...w-palmetto) If it doesn't help those symptoms, as an antiandrogen would be expected to, is it a very powerful antiandrogen, or even one at all?
In any case, SP apparently did not do much for my system, despite some laboratory assay comparing 5-alpha-reductase activity with finasteride. Remember in vitro studies do not equate to what happens in the body.
I am not totally sure if it was the FG or the SP that piled on the pounds, but one of them definitely did. There is anecdotal evidence that SP does promote weight gain:
Quote:Native Americans ate the berries of the saw palmetto believing they served as a tonic that nourished the body, stimulated appetite, and promoted weight gain.

In addition to NOT helping regrow hair or stop hair loss (another likely function of antiandrogens), check out this information on interactions with SP from WebMD:
Quote:Birth control pills (Contraceptive drugs) interacts with SAW PALMETTO
Some birth control pills contain estrogen. Saw palmetto might decrease the effects of estrogen in the body. Taking saw palmetto along with birth control pills might decrease the effectiveness of birth control pills. If you take birth control pills along with saw palmetto, use an additional form of birth control such as a condom.
Estrogens interacts with SAW PALMETTO
Saw palmetto seems to decrease estrogen levels in the body. Taking saw palmetto along with estrogen pills might decrease the effectiveness of estrogen pills.

SP also has other documented side effects:
Quote:Side effects from saw palmetto are not common but may include headache, nausea, vomiting, upset stomach, dizziness, constipation or diarrhea, trouble sleeping, and fatigue. Its long-term effects and safety have not been studied.

The only side effects I could find with regard to pygeum africanum are pretty much what you would expect from any benign herb:
Quote:SIDE EFFECTS: Constipation, diarrhea or nausea may occur.

My point in posting the original link and mentioning pygeum africanum is that it IS an effective anti-androgen that seems to work in ways that SP does not, and it doesn't have the same suite of potential side effects. A quick search on the net (wikipedia for god's sake!) shows that in addition to whatever effect it has on 5-alpha-reductase activity, it also has other androgen blocking constituents and properties. Two (or more) for the price of one!
Quote:The compound N-butylbenzene-sulfonamide (NBBS) isolated from Pygeum africanum is a specific androgen antagonist.[7],[8]
Pygeum africanum contains an antiandrogenic compound atraric acid.

The wikipedia article includes references for further verification, and I found similar information elsewhere on the net while doing more research.
Also consider this information when basing your choice solely on a comparison to finasteride:
Quote:Finasteride (Proscar, Propecia) and dutasteride (Avodart), inhibitors of the 5-α-reductase enzyme that prevent the conversion of testosterone into dihydrotestosterone (DHT). Finasteride blocks only 5-α-reductase type II, dutasteride also blocks type I. They are not general antiandrogens in that they do not counteract the effects or production of other androgens other than DHT; however, DHT is 3-5 times more potent than testosterone or other androgens (except in skeletal muscle tissue, where testosterone is the main androgen).There are a number of in vivo and in vitro plant/herbal inhibitors of the 5-alpha reductase
http://en.wikipedia.org/wiki/Antiandrogens
The point of that last quote is that finasteride is NOT considered a general antiandrogen and may not be very useful in comparison to other general antiandrogens.
In light of the evidence above, and the facts that you are taking PM and SP, and you aren't seeing the results you desire, you might consider stopping the SP!
I am merely pointing out some interesting information. It's up to you how you want to use it, or not. However, minds are like parachutes, they only work when they are open.
Cheers.
