yes water is bad for CB. Same issue with RU.
I only use the 95% ethanol now, don't like the PG greasy feel.
A lot of people have not had results on CB because either they use not enough of it, or the vehicle is not appropriate, the CB is being un-disolved or degraded in it over time. Mostly a combination of those factors is the cause.
I mix my CB with Ethanol just before application, don't want to waste any of it as its expensive
If you look at the studies, the ball park is 150mg to 300mg a day, that is expensive when using the Chinese CB
