I wrote the company IV For Life to ask about their Glutathione, this one: http://www.amazon.com/gp/product/B00..._cart_cp_2_1_p, and the owner responded with all the helpful information I wanted, since I'm very careful about the products I use and what goes into them. This one still has some things that I don't care for, but I guess you need some preservative for this substance - every company has it - and some flavoring, since glutathione apparently tastes horrible. Anyway, he then offered to give me 50% off, if I liked it and wrote a review on Amazon. He then also offered me 100% off/refund, if If I purchase and use and benefit from his two new products:

http://www.amazon.com/Optimized-Lipo...th+resveratrol

http://www.amazon.com/Optimized-Lipo...om+IV+for+Life

I asked him if I could share this with others and he said he could extend the offer for a few dozen people. I don't plan to use these two other products, because they have ingredients I don't care for, but I will be ordering and using the glutathione. Anyway, just in case people are interested. Here's his/the company's email: info@ivforlife.com.
