High Dose IV Vitamin C has been used for years and started in the 1970's. It was made popular by Dr. Myer. 

The pharmaceutical and 124 BILLION dollar cancer industry is scared of it's therapeutic and cancer fighting power because it is not a patentable drug.  Drug companies can not patent and monetize natural elements and compounds.  Luckily recent refocus on high dose vitamin C research has begun and we are seeing very positive results. Multiple clinical studies have shown that High dose IV Vitamin C drastically assists in recovery from viral infections, extends the life of terminal cancer patients, reduces debilitating side effects of chemotherapy and other cancer treatments.  There are currently more than "X" studies evaluating the rejuvenating powers of high dose IV Vitamin C including cancer and disease prevention. 

Quick history of Vitamin C
45 Million years ago a genetic defect caused primates to reduce the resting level of vitamin C in the bodies.  For example Goats have 

 

Humans and higher primates, as well as guinea pigs and small number of other animal species, carry a mutated and ineffective form of the enzyme L-gulonolactone oxidase, the fourth and last step in the ascorbate-producing machinery. This mutation likely occurred 40 to 25 million years ago (in the anthropoids lineage). The three surviving enzymes continue to produce the precursors to vitamin C, but the process is incomplete and the body then disassembles them.

In the 1960s, the Nobel-Prize-winning chemist Linus Pauling, after contact with Irwin Stone, began actively promoting vitamin C as a means to greatly improve human health and resistance to disease. His book How to Live Longer and Feel Better was a bestseller and advocated taking more than 10 grams per day orally, thus approaching the amounts released by the liver directly into the circulation in other mammals: an adult goat, a typical example of a vitamin-C-producing animal, will manufacture more than 13,000 mg of vitamin C per day in normal health and much more when stressed.[29]
