How many times one can have I.V in one vein in one week?

I am undergoing I.V. Hydrogen Peroxide and HVB treatment for genital herpes II. May I know how many times one vein in one arm can be poked each week? There are advertisment in Mexico that they do 2 I.V.'s each day for 5 consecutive days as a package of treatment. And I was thinking to see 2 doctors for 3 I.V in one week, if my vein can tolerate. Booking is always crowded in one doctor. I only feel good with hydrogen peroxide, and not even HVB or Major autohemo therapy.
