Opana, or Oxymorphone, is a powerful pain-relieving drug and has been classified as a narcotic, or opiod, pain reliever. It works by affecting the parts of your brain that can help you to not feel pain and it is very effective in this sense and its effects last longer than most drugs. Opana is also sometimes used to maintain anesthesia before being operated on. You can buy Opana online through us without prescription as well. This is very helpful for people who are in constant pain and no pain medication seems to help them.
