Medisca, I would assume, has specific reasons they decided to use that specific formula. Although I do not claim to know the reasons, I would find it reasonable to assume there is a logic to their madness, otherwise they would open themselves up to legal liability. As a result, I feel more comfortable following these instructions than I do some of the bro-science found online. I have learned a lot from many people who contribute to this forum, and am appreciative of any and all feedback given.
In addition, I have enjoyed trying different formulas, esters, carrier oils, and will likely continue to do so until I find the perfect combination(s) for me.
