From M.E. back to "me"

Vitamin B12 in Gerson Therapy is administered by intramuscular injection into the gluteus medius muscle, 0.1 cc (100 mcg) once daily for 4 to 6 months or more. It is accompanied simultaneously (in the same injection syringe) by 3 cc of crude liver extract.

Kutapressin was an injectable extract of porcine liver, made by Schwarz Pharma since the 1940's. It was licensed to treat acne, excema, cold sores, herpes viruses and other inflammatory viruses. It reportedly did well with treating shingles and chicken pox as well. The treatment of these viruses drew attention of the ME/CFS research community, as some report a viral component to the disease. Kutapressin's treatment of viruses, inflammation and its effect on the immune system seemed like a good fit for ME/CFS and has shown some promise in trials where patients used the injections for 6 months or more. Several years ago, the company making Kutapressin discontinued the product for financial reasons, but the company Nexco Pharma created the virtually identical Nexavir in its place. Many ME/CFS doctors use the names interchangeably. The main difference I've seen is that Kutapressin did not have some of the additives and preservatives contained in the newer Nexavir version.

According to Wikipedia, Hepapressin is an amino acid complex prepared from Argentinian bovine liver. It is used to normalize immune dysfunction. similar to Kutapressin which was previously used in these conditions. Hepapressin does not contain preservatives and should be refrigerated. Hepapressin is used in ME/ CFS and Fibromyalgia. It is considered to act on the methylation cycle which may have a defect in ME/CFS.

Liver extract for the purpose of injection can also be obtained with a doctors prescription from a compounding pharmacy. There is also information in the links below that refers to similar protocols using liver extract in the treatment of MS fatigue.
