Anyone? Discount vendors seem to be out of stock and prices are rising. New brands (Manna, Theracyn), etc. Any info on what we should be buying and where? I used to buy for 13 dollars, now they are anywhere from 22 to 28 dollars.

Last, any information on a clinical trial for bladder instillation on humans? Some here have been using this for 5 years or more, it seems that the market for instillation would be substantial, I am curious as to why there is no information on a clinical trial. I go through a 16 oz bottle in 10 days.
