In 1986, California voters approved an initiative to address their growing concerns about exposure to toxic chemicals. That initiative became the Safe Drinking Water and Toxic Enforcement Act of 1986, better known by its original name of Proposition 65. Businesses are required to provide a "clear and reasonable" warning before knowingly and intentionally exposing anyone to a listed chemical. You may see a lot of supplements with a prop 65 warning. NOT KAGED MUSCLE. Just another reason you can be confident in us and our products. #KM #Wetestwedontguess #Thestandardhasbeenset
