Pfeifer Protocol - any thoughts?

Just wondering if anyone has looked into Prof. Ben L. Pfeifer's protocol?

There is a mention of product/agent called Prostasol, which I've seen discussed on this site before.

Claims are 65% success rate with high risk PCa.

Prof. Pfeifer appears to be located in Switzerland and seems to have many publications to his name.

It says "this will effect immune response".

The correct word is "affect". No points. Like the chocolate M&Ms.

I was a bit leery of Pfeifer when I originally came across the protocol. & that is because of the ProstaSol connection.

My understanding, based on 3rd-hand accounts, is that the U.S./Mexican & Dutch ProstaSol formulas started out the same, but diverged. Even so, both were eventually shown to be spiked wih DES. Eventually, users reported that the products were no longer working - no more DES, presumably due to unfavorable publicity.

I have pasted the section on Prostasol from your link, below [1].

One thing not mentioned is that Pfeifer (so I was told) was instrumental in setting up MedPro. & it was he who arranged for a Swiss test, which turned out negative.

[2] & [3] tell a different story.

(I thought that Pfieffer retired.)


[1] "Is there any truth in the rumours that Prostasol works because of estrogenic contamination?

There are a few individuals and organisations putting out information that ProstaSol works because it is contaminated with estrogenic compounds. (A few years back there was a Chinese herb prostate formula called PC-SPES that was contaminated in this way.) Medpro ProstaSol is manufactured in the Neterlands under the very strict standards of GDP, GMP and HACCP, and this ensures that there is no estrogenic contamination. In fact, Dr. Pfeifer himself, aware of this possibility, organized for Medpro ProstaSol to be tested independently in a Swiss lab, and the results are negative contamination. Please note, however, that this assurance only applies to the Medpro version of ProstaSol and not to any other product bearing this name."


[3] (from something I posted in 2008):

"the Danish Medicines Agency issued a warning two years ago that "Prostasol" had tested positive for DES (

"Warning against the product Prostasol with oestrogen

The Danish Medicines Agency has become aware that the product Prostasol, which is sold via foreign websites, contains oestrogen without this appearing from the packet.

The description of the contents states that Prostasol is a pure herbal product, but a Danish analysis shows that Prostasol contains diethylstilbestrol (synthetic oestrogen). Products with diethylstilbestrol are medicinal products, just like other products with hormones.

Prostasol is often used as a dietary supplement for patients with prostate cancer.

Prostasol is not authorised by the Danish Medicines Agency, as such products must be, and we therefore warn people against using it.

The Danish Medicines Agency encourages people who have bought Prostasol to stop using it and hand over the remaining part of the product to a pharmacy.

For further information, please contact Lisbeth Lund Hemmingsen, tel.: +45 4488 9746."

A Danish letter was posted to the other board on 6/1/2007. This time the spelling is "ProstaSol" (this is the Dutch name; the small "s" is as in the old Mexican name):

"The Danish Medicines Agency has little information about ProstaSol, but it's a dietary supplement containing extracts from saw palmetto, scutellaria, ginsing, skullcap, reishi, ginger, stinging nettle, pygeum, as well as quercetin, resveratrol and a sitosterol mix. It's

used as a complementary therapy-product for patients with prostate cancer, and it's sold by many companies. We can't send you much information relating to research results, from the diethylstilbestrol-analysis. The analysis is done in October 2006, and show that ProstaSol contain 801,56 microgram of diethylstilbestrol pr. capsule. The analysis is done by: Institute of Public Health, Research Unit of Environmental Medicine, University of Southern Denmark.""


Thanks very much Patrick.


Paul, I would steer clear of any treatment for PCa that has never been published in a peer reviewed medical journal and this applies to Prostasol. Also, 2 of the main ingredients, saw palmetto and pygeum, have previously been proven to be useless in the treatment of PCa.
