I have heard nothing about them, but I don't like the fact that their site for the frogs and toads vitamins do not indicate what their formulation comprises in a % or IU breakdown. Nonetheless, if Phillipe de Vosjoli is involved on some level, that at least lends some credibility to them.
By the way, what vitamins/minerals have you used that you have found to be better than RepCal and Herptivite?
