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 advertisement 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's in one week, if my veins in both arms can tolerate. Booking is always crowded in one doctor. I only feel good with hydrogen peroxide and not even HVB nor Autohemo therapy. Thanks.
