Although there are products that claim to be substitutes for PCS MATRIX, they are not the same. Few of these products have been the subject of laboratory or clinical trials reported in the peer-reviewed medical literature. These two supplements (PCS MATRIX and POMI 10X) are formulated specifically for the sole purpose to alleviate symptoms and lower PSA. There are no other products that do this with 100% natural ingredients. All one has to do is take enough of PCS MATRIX and POMI 10X to get results. We've worked tirelessly to improve an already great 100% natural product and this one is the best so far. We were able to refine and make available a more potent formula for all of us. Dosage is 2-8 pills a day according to your charts and we have to say, we are extremely impressed. We truly feel all of us will find this formula superior and it's results have proven it. The key 14 ingredients are strong and more readily absorbed by the prostate for better effectiveness. This new formula is purer and stronger than it ever was. PCS (Prostate Cancer Support) MATRIX contains herbs that was developed by Dr. Eric Llewellyn. PCS MATRIX is the result of ancient wisdom and modern science. It contains Saw Palmetto, Rabdosia, Scute, Pseudo Ginseng, Plantago Focium, Resveratrol, Chrysantaomum, Isatis Focium, Cyathula, Ganoderma, Lotus Seed, Lycium Bark, Schizandra and Liquorice. PCS MATRIX works in several ways, it improves the immune system and induces apoptosis (programmed cell death). Almost 70% of hormone refractory prostate cancer patients observed a decline of their PSA > 50% in a trial. Dosage was 6 to 9 pills 3 times a day. *FOR MORE INFORMATION AND DOSAGE RECOMMENDATIONS, PLEASE CONTACT MANUFACTURER
