It's literally 30-40 minutes for me. Too short for the price range.
A number of other people have reported it lasting maybe slightly shorter than MXE but more or less really similar in duration. Keep in mind some people have a lot of disso tolerance. It might last super short for you but don't take one user who was recently binging on ketamine's experience as how the drug will act for you.
