The best way to figure out whether your brand is legitimate is to check if they submit their products to third party lab tests for both potency and purity. This way, you’ll know that if a salve says it has 300 mg of CBD, this is a true statement. Anyone can make a claim, but unless they back  it up by science, you could just be buying an overpriced lotion. Third party lab tests also test for toxins and artificial ingredients you may not want in your cream.
