I bought some fermented cod liver & butter oil from here:http://www.greenpasture.org/public/Prod ... /index.cfm
So there's the price. I got the gel instead of the capsules since it's cheaper and I can handle the taste. (I don't savor it; I just swallow a little and wash it down with milk).
I was already taking 2000 IU Vitamin D recently; not going to up it since I haven't yet been tested for Vitamin D levels.
Cold showers aren't my cup of tea.
I can't really say anything regarding results; my libido has increased recently, but I have been eating more (Occam's Razor), so I can't say if there are effects purely from the cod liver & butter oil. I simply felt like trying them out of curiosity and there are other nutritional benefits besides the testosterone boost.
