Kilosports stuff is PROBABLY good, I have ordered several items from them in the past and love the prices, but the problem here is YOU JUST DON'T KNOW with Kilosports. Since you're talking about your liver, you probably want to be more certain. So far I am shelling out bigger $ to buy a known brand from the drugstore. Even a generic grocery store brand is at least backed by a major chain store as opposed to being shipped out of some warehouse in Arizona in bulk and sourced from China (with no particular guarantee that the source is consistent).
I believe places like Kilosports have fudged things here and there, like selling 8 different prohormones with different prices, but putting the same andro product in all of them...
