I can't give you much to go on but I've read on PR a few times of a 'kit 'that contained alpha lipoic acid, acetyl L-carnitine and something else. The kit was labelled as an acronym with 4 letters in it, one of them might have been a K and maybe an X? I think Cort J once posted about it. OMG...this looks like a riddle! It's not!! I really would like to look into the efficacy of these 3 supplements when taken together through this brand (or supplier?) Thanks!
