Hi all, I have tried two types of colostrum in the past plus lactoferrin and it did absolutely nothing. I am trying to look into transfer factors because I suffer from way to many viral, bacterial, and parasitic infections. That probably has to do with the fact that I have an Immune deficiency for which I use Gamma Globulin in addition to CFS. I also geta ton of inflamation. I am looking for good feedback as my budget is very limited on your experiences and if you liked which one. I am also confused which transfer factor targets whats so you help is greatly appreciated. I have tried so many supplements that do nothing I cannot afford to waste. Thanks again for your help.
