Buy Oxycodone online is a powerful painkiller, used to treat moderate to severe pain. It works by blocking the effects of natural chemicals in the brain that are responsible for causing pain sensations. Oxycodone can be obtained by prescription, but it's also available on street drugs such as heroin or morphine. When you take Oxycodone, your body will produce more than one type of opioid called endorphins—feelings of euphoria are common after taking this drug because they block out any negative feelings associated with withdrawal symptoms like anxiety and depression.
