We are not in a position to make claims about the use of our products. We encourage those considering this approach to first have a look at the official research done into the use of GcMAF for many types of cancers, which you can view at the PubMed website here. Please have a good look through the various trials and academic papers to decide if this is something you would like to try. For a more aggressive approach, our customers generally choose our highest strength products, most notably our Super Strength Cream and Sublingual Spray.
