Yes, at Kandy Girl it's our first priority to keep you safe. And that starts with 3rd party lab testing all of our Delta-9 THC Gummies from a DEA registered lab.Most companies don't even test the potency of their products, and if they do they only do it once. All of our gummies are tested for not only potency, but heavy metals, pesticides, microbes, and residual solvents.
