GcMAF stands for GC protein-derived macrophage-activating factor and is a protein that occurs naturally in the body.
GcMAF is said to stimulate specific immune cells (macrophages) and thereby activate them to fight cancer cells.
The usage of GcMAF in cancer treatments is not recommended.
I do not recommend using GcMAF in cancer therapy. The drug is expensive, and I can say from my own experience that this substance has shown no effectiveness in numerous treatments.
