Where did I say that there is anything that stops the progression of MS for all those diagnosed with MS? Lots of treatments claim this - LDN being one. But nothing works for everyone. Some people swear by Avonex. Some people swear by LDN. Some people swear by Esperanza Peptide, and some swear by Miracle-Mineral-Supplement . It doesn't mean that it works for everyone, nor does it mean that it doesn't work for some.
