Ketamine is the first legal psychedelic medicine available, which can be used alone or in combination with psychotherapy for the relief of treatment-resistant depression, anxiety, chronic pain syndromes, PTSD, substance use disorders, autoimmune disorders and many other conditions. Experts at the National Institutes of Health have stated ketamine is “the most significant breakthrough for treating

depression in half a century.” Ketamine therapy is considered a promising alternative to traditional antidepressants, pain relievers and other psychiatric medications which can take weeks or months to work.

"Over the past 2.5 years I’ve tried an initial regime of IV ketamine, then at home lozenges, then a series of IM ketamine with KAP. I wish I knew of Quest Ketamine first. It would’ve saved me both $ and time. With the help of Mitch and the crew at Quest I’ve been able to discontinue the last difficult to quit anti-depressant (venlafaxine)!!! With 4 therapy rooms and both daytime and evening hours it was easy to schedule.." says Lorrie on Google
