Interesting....Didn't even know they made that. Since it is over the expiration date, I would try to give the company or some sort of lab a call to find information if it is stillactive...I dont think anyone could answer that question for you accurately.
Are you talking about ingesting a topical cream orally using gelcaps? One would think that would be dangerous, how do you know how much active ingredient you are ingesting? I do know Ketamine OD is rare by itself, but I would worry about other substances in this topical cream to be toxic to the body..
sorry I don't have a solid answer for you, good luck
