Well I had seen something on here yest, from some of the "iodine" posters, and they are in the know , and also I saw a while back on earthclinic.com by "Ted from Thailand" the resident chemist on there, Where he mentioned taking Boron or actually ingesting "Borax" in a solution to boost test and/or help with libido , etc. but thanks for your info on the zinc/copper ratio.
