I began using Hello Blue’s Muscle Butter ACTIVE during the summer as a way to warm up before workouts. I’d put some on my shoulders and quads. It really seemed to have an effect, but I wasn’t sure whether that was from taking CBD oil, or the direct application of this butter. But then I started using it on my thumbs, which both have mild onset of arthritis (thanks, smartphones). Within a couple of days, that pain literally disappeared. It’s unbelievable what CBD is capable of when it comes to aches and pains. I highly recommend this product.
