Transparency: cbdMD seems to be going through a transition with their third-party testing practices. Until recently, they only released a lab report for the CBD concentrate they use for all their products, but would not show potency testing for individual products. That seems to be changing. Currently, the only lab report on the website is for their concentrate (and it’s over a year old). But if you contact customer service, they’ll send you a lab report for any product.
Most products labeled "hemp oil" do not contain any CBD. Those are typically hemp seed oil which is more commonly used for cooking or to make salad dressing. If you want to buy CBD oil, you'll want to look for products that are labeled "CBD oil" or "hemp extract." To confirm that a product you're interested in has CBD in it, you'll want to look at their third-party lab reports. All reputable companies selling CBD oil products will make third-party lab reports available to you to confirm the presence of CBD.
