Some companies will hide under a cloak of darkness that the Internet can provide, but it’s a pretty good sign if the company lists an honest-to-goodness phone number you can use to reach real people. The companies with inferior products will often be very difficult to reach. Before ordering, try to reach out to the company. If someone picks up the phone or gets back to you in a timely manner, you’ve probably found a company that not only takes accountability seriously, but cares about their customers and the quality of their products.
The manufacturer will probably give you a recommended dosage, but bear in mind that this isn’t set in stone. What you need to find is your own minimum effective dose. “Minimum effective dose” is a medical term which refers to the amount of a substance you need for the results you want, and above which, the substance doesn’t increase in effectiveness.
Once companies have these test results, sharing them with customers is not just a best practice—it should be a priority. After all, you shouldn’t have to guess what’s in the bottle or wait to read results until a product arrives in your mailbox. That, says Diamond CBD, is why their team makes test results for CBD oils and tinctures available online, right next to the product description.
Receptra Naturals CBD products are derived from proprietary CBD rich hemp, grown on family owned and operated farms in Colorado using 100% organic farming practices on select organic soils without the use of pesticides or fungicides.  I got to know the folks at Receptra while dealing with Charlotte's Web Botanicals and continued to stay in contact when they left CW to form Receptra. 
GMP stands for Good Manufacturing Practices, and it covers the practices required to ensure products are produced according to industry standards. The agencies that control the authorization and licensing of the manufacture and sale of these products provide guidelines, and the manufacturer must adhere to these guidelines to make sure their products remain consistent and of high quality from batch to batch.
The formulation, however, offers optimized delivery via mucosal membrane permeability in tandem with precision production/formulation methods. Her company, HERBOLOGIE, reduces the particle size of the cannabinoids and immerses them in a matrix of exclusively natural ingredients that work synergistically to enhance absorption through oral membranes. When cannabinoids are transported through membranes and directly into the bloodstream, the phytonutrients are delivered more quickly, and crucially, avoiding first-pass degradation in the liver.  
E-liquids offer a way to take in cannabinoids via the pulmonary versus digestive system. There is research to show that this allows the cannabinoids to get to work more quickly in the body. These products also start with a raw oil or a chrystallized version of CBD, known as isolate. Flavoring is added along with a carrier – which may be a combination of vegetable glycerine and propylene glycol or MCT (fractionated coconut) oil. These are all odorless liquids that produce vapor when heated, which allow them to be inhaled. We do not carry any E-liquids that include nicotine.

Honestly, you can find CBD oil just about anywhere. Went on a cross country road trip this summer and was laughing at the “CBD for sale here” signs in these tiny little nothing towns. My experience? Buy the good stuff online. I’ve heard consistently good things about Elixinol, Purekana and green roads. Honestly don’t know what the hell this stuff is that they’re selling all over the country, but I’d stay away from it
Dogs and cats are known for their powerful sense of smell. They typically don’t like having something new added to their food, making supplementing their diets to ease health issues challenging. However, CBD products for pets take that challenge into account. Developed by dedicated veterinarians, they’ve been designed to pass the taste and smell test.
Hemp is a bioaccumulator, meaning it is capable of absorbing both the good and the bad from the air, water, and soil in which it’s grown. This makes it all the more important to know that your CBD oil comes from organically grown hemp that can be tracked to its US-grown source. The last thing buyers want is for their CBD oil to have accumulated toxic substances such as pesticides, herbicides, or heavy metals. For decades, farmers have used pesticides to protect crops against insects, disease, and fungi – and have used herbicides to control weeds – but we’ve known for quite some time that chemicals used to harm other species can also be harmful to our own species. That’s one big reason behind the global push to go organic. People are starting to prioritize organic crops, whether you’re talking about fruits, vegetables, grains, legumes, nuts, livestock feed – even textiles like cotton, wool, and flax.
