I can not see anywhere him sells supplements.

And where do you got your information from , please tell me.
And even if you where right PM.

I'm still against vaccination for many, many reasons and I can find you article upon articles that speak out against vaccination , if you don't like to hear it from Bill Sardi!!!

I just trying to warn people , but nobody wants to hear it , so I have done my part in warning, you can take it or leave it.
Bill Sardi or not, I have know about the dangers of vaccination for a long time and did my research!
