back pain
"(Male, 42yrs, 220lbs, active/athletic). I take 375mg once in the morning for the relief of occasional (4-5 times a year) severe back muscle pain. While it unfortunately takes 2-4 hours for me to feel the effects, when it has been absorbed it gives me 90-100% relief and the benefits last for roughly 48 hours. This is by far the best pain reliever I have ever used. As for adverse side effects, luckily I can't seem to detect any. "
