I don't get the impression it is an MLM.
The impression I get is that it is a very expensive, support 'group' for anxious parents of anxious teens. All dressed up as a special formula with a very hard sales emotive technique.
I think there would be some benefit, as just feeling there is someone there to hold your hand 3 times a day for as long as needed and to point out obvious things you as a parent are doing that don't help the situation will be beneficial. Plus sessions for the young person so they feel less alone.
I question however whether any of these benefits will be sustained and continue to increase once the initial euphoria has worn off.
An MLM is characterised by recruiting downlines and buying stock yourself, fake it til you make it, and don't let the haters get you down.
