Any Updates on Insulin Potentiation Therapy (ipt)

Insulin Potentiation Therapy (IPT) was raised in a discussion almost two years ago. As usual for alternative treatments, some anecdotal reports recommended it, but solid evidence was lacking. It's been around for some time now, and if it works, there should be more testimonies to its success. Is there any updated information on IPT? Has anyone undergone this treatment or know of someone who has?
