The key is to effectively gauge exactly how much CBD oil it takes to start managing your pain. If you start off right away with a maximum dose of a 600 mg tincture, you will have no idea how much of the product it actually took to treat your condition, and how much you wasted (this is also important because you do not want to exceed dosage and end up developing a tolerance to the active cannabinoids).
Formulation strength is where you'll notice the biggest misalignment between price point and customer interest. You'll find companies offering 2000 mg or 3000 mg formulas. Not many people are buying these. Instead, they choose formulations that are less potent, less expensive, yet still effective. For most retailers, it makes sense to focus in on these products.
