Hi,[this]( https://ca.iherb.com/pr/crystal-star-herp-defense-60-vegetarian-capsules/57437?gclid=Cj0KCQiAwJWdBhCYARIsAJc4idB25WBUD18hydnnaGYvjAHR_OrNu3BANpZe32kHp-FFGYKIcFrssA4aAqVrEALw_wcB&gclsrc=aw.ds) is the only product that I’ve ever came across with multiple testing with my previous patients, it does work really well, but have to be used at a therapeutic levels, of taking 2 capsules 3 x times a day, and sometimes more depends on how extreme the issue is. And it will not fix within overnight, it could take 45 to 90 days before we see a progression reversed.
