No More Mosquitos

Posted by 5102247090103082160 on Jun 06, 2014

I bought this specifically so I wouldn't get bit by mosquitos. I've been taking it about 3 weeks. So far I have'nt been bit one time. And I've been in some pretty bugged-out areas. I hope it works all summer.

Been taking conscientiously with other supplements, cant actually tell if it is beneficial on its own but on the overall, i do see my health improved.
