Below, Although a different brand, I strongly suggest also getting this book and studying this site.
Allicin is best a part of plan, and this source suggest it be dosed according to one's weight. Call and talk with Hepapro about their chart.
Biopure is also an excellent brand but I think it's vital to read from this LL author, too, as well as from Dr. K - so that you have a full range of information about allicin.
