I've been using it for arthritis pain for a year or so. Ive tried about 12 different brands with varying results. I have found at least 10 of them to be ineffective or poor in effectiveness. My main finding is that full spectrum is a marketing ploy. I use a concentrated cbd extract now, and it works perfectly. The full spectrum promises better synergy with your bodies mechanisms as it includes the oils from the seeds, stems, leaves etc, but really what you getting is less and weaker cbd, while the companies selling it don't have to isolate the cbd, they can package the oil as is. I have done tons of research, spoken with a handful of "professionals", and like i said, tried many brands on myself. I am 98% pain free from my knee and hip arthritis, but only when using the cbd. If i miss taking it, or take an inferior brand, I'm up all night in pain. NHBULL, pm me and i can tell you the brand i take, its independently tested for potency and purity. The potency is always much higher on the test results as compared to the label. I use the 1200 milligram bottle, and the results are often in the 1450 range, free cbd.
