Hi, the GCMAF clinic does have success treating cancer patients with colostrum in the mix. they put patients on keto diet, only white meat and veg.. add in Bravo yogurt and gcmaf injections.. the Bravo yogurt is cultured with colostrum and together creates gcmaf .. note: not all folks respond to gcmaf.. its predicated on VDR gene receptor activities.. if you dont process vitamin D well genetically you wont respond.. thats about the only way I would sanction colostrum.. also if you get a hold of some or a kinesiology specialist they can muscle test you for response.. google is thy friend.. much love and happy healing.. - cancer healing now..
