Doctor Constantini explained as follows:
"we use thiamine hydrocloride intramuscular phials or tablets taken by mouth. Generally, with the oral therapy we start with 2 grams each day to be taken once a day in the morning, in order to increase the dose later consequently to the results obtained. The oral therapy is as effective as the intramuscular one. Some follow-ups of the results are always necessary"........"in the experiment we used thiamine hydrochloride. Thiamine administered intramuscularly is 100-140 times stronger than the equivalent oral dose, depending on the personal patient's absorption. So, for example, to have the clinical effect of 1 im injection once a week, we have to administer 2 grs orally each day for 7 subsequent days."
Addressed to me, Roy, Doc Costantini's recommend: “For your situation 1 intramuscular injection twice a week (or an oral dose of 4 grams each day, two tablets in the morning and two at lunch time) should bring to the complete regression of the symptoms in 1 or 2 months.”
Note the dose in the morning and again at lunch time.
