Yes, I'm saying that D2SO4 products differ from H2O2 (Hydrogen-Peroxid) and stabilized O2 products. The end result -- more oxygen in the body -- is shared among them. It's mostly in the "how?" and "how well?" that differs.
As to which is better... I don't have enough information on what you consider "better" to be able to answer that question for you. My preference at the moment is the D2SO4 products, but since I haven't tried the other ones, my opinion might be biased just a tad.
*grin*
Perhaps a comparison of oxygen therapies would be useful here. I'll look into compiling something for this, unless someone else beats me to it....
