That is a hard one i have read a lot about tx and them antivirus and it is not for me the side effects are real bad and what the F.R.A is in a lot of trouble.I have hep c and i am at stage 3 and i am trying advanced Colloidal Silver ,i have only been on it three weeks and i guess i will stick with it for a while and see what happens.So i would say to try the herb way that tx scares me.And so does the F.R.A.big money for the drug companys.Good luck in making your choice.
