I used it was great boast in appetite and energy for me. I do or did 3 cc's EOD 1 1/2 cc's per glute.
Mine was 100 cc given from a friend for the price (free)
I liked it go to e-bay and can get all the time for well under 50.00.
It contains potassium also which is good for you along with B-12 and other things.
Its like $70.00 at www.kynoselen.com a bit of info's also but save 20.00 and buy on e-bay.
