that's what it said in the magazine. we'll see. i'd def buy if it was cheaper
I'd NEVER buy that, especially not if it is cheap!!
With milk, you have sort of an idea where it comes from and what is in it.
If you have "fish powder", you will have all sorts of nasty shit in it that is normally not available for human consumption, it will be sort of surimi in powder form, absolutely disgusting.
If you want fish, buy some tilapia or other white fish frozen, it's cheap and easy to make, or throw it into a mixer with some aroma, this will be much safer than buying "fish powder".
