I've done that with my yb's Ryan but never got them tested so dont know if it done them any good or not? I have also used a tablet crusher to turn them into powder and put them on the feeding along with a little oil at times aswell.. I got the 500mg tabs the last time i was in Turkey 2 years ago i think i got 6 boxes still got a couple left yet but i will get more when we go back this year after the racing
