GCP Research

Is there any research on GCP and prostate cancer (PCa)?
Currently, Dr. Aaron Katz of Columbia Medical Center (Center for Holistic Urology) has performed several studies on GCP in both animal models, and in his patients. Two of his research papers on GCP have been accepted by peer reviewed medical journals, and one was published this August 2002 in the Journal of Alternative and Complementary Medicine. V.8, No.4, pp.493-497.

In Dr. Katz’s in-vitro experiments, GCP successfully killed prostate cancer cells. In his human trial, GCP was concluded to have “…some potential activity in the treatment and prevention of prostate cancer.” (J.Alt Comp Med). The biopsy proven prostate cancer patients in the trial consumed GCP for 44 days at a 2g dose, and their radical prostatectomy specimen revealed no cancer. Yet, the PSAs of these men varied in the 44 day period. While some went down or stabilized, some went up. He concluded by saying that PSA may not be the best way to determine the progress of the disease since he found improvements regardless of PSA changes. Furthermore, the trial was too short in duration, and GCP dose was too low. Natural compounds are usually found to demonstrate their effectiveness gradually over many months, and dosing often needs to be high when aggressive disease is present.

Lastly, the Man To Man prostate cancer support group did an informal study on GCP which lasted over one year for some men, and included doses varying between 2 and 9grams. The results showed that GCP did significantly help lower PSA when original PSA of these men was below 10. Also, the higher the GCP dose, the better the results, and taking AHCC in addition to GCP significantly helped achieve better results, especially in quality of life parameters.

Animal research from Japan confirms that combining GCP with AHCC in an equal dose of 3grams each, provides the most promising results in shrinking the prostate tumor, anti-angiogenic activity., and apoptosis.

What type of results have been seen in PCa patients using GCP?
