I heard a blurb on the radio today but do not know where it came from. Seems they did a double blind study where they gave some 20 year old athletes colostrum and the others a placebo. Seems that the ones that got the colostrum had 20% more endurance. Best thing about this is it is not a drug but a food so can be sold without FDA approval. I don't know if they got human colostrum. Anybody else hear it? or know of it? Vivian Derr, PNP
