in the first post it mentioned that they were also given "the second group was given propionyl--carnitine 2 g/day" what kind of difference would just taking alcar make instead of the propionyl? since seemingly alcar is all everyone is taking. Or is it just the same compound with a diffent "ester"? attached to it?
Not sure if its really an ester or not, but I'm taking a random shot in the dark and thinking its the same base compound just slightly different, like the different types of test?
