I think glandular thymus and thymic protein can come out to be about the same thing as long as u take the thymus away from food and on an empty stomach to avoid stomach acids. I dont think the Thymic protein is that expensive. It works out for me to USD$1.30/packet a day. Comparing that to Cycloferon its about the same. I am trying to get a source that can get it dwn to $1 a packet. Btw that and all the other stuff I am taking, I am feelg pretty ok. I also take another supplement called SST (sho-saiko-to) that has been researched to increase interferons. I knw that it has been recommended for Hep C patients when they cannot tolerate Pegasys treatment. The SST is rather pricey but the main ingredient in it that actually induces interferons is Licorice. I have taken the herb on its own, I love it. It is cheap and when it works it makes me feel great. Do you have an opinion on Famvir and generic Famvir ? All I cud get was the generic one.
