If you are in Europe you could just use pantostin/alfatradiol/ell cranell instead of Everclear since it is in an ethanolic vehicle anyways. Probably not very different in price and you would get the benefits of the alfatradiol on top of those of the RU
If water fasting does in fact work for PFS (which I doubt it does) then that pretty much completely blows apart their theory that it is caused by androgen receptor desensitization. How would fasting possibly effect that.
