Ketamine is an anesthetic, a medication used for induction and maintenance of anesthesia. It is one of the safest anesthetics, as, in contrast with opiates, ether, and nitrous oxide, it suppresses neither respiration nor heart rate. Some anesthetics are flammable or explosive, but ketamine is relatively easy to handle safely. Ketamine is a novel chemical created in a quest for a safer anesthetic, safer than the PCP from which it is derived. Buy Ketamine Online.
