i wasn't very impressed. he used SHIN as an anacronym for sleep,hormones,infection,and nutrition. he mostly talked about his supplements and said he did not take any money from them.if you read the labels they are nothing special. he said the test ranges for infections and hormones were not reliable but did not tell how you should determine what you might need. he said we had basicly "blown a fuse" . this is not a medical term and he did not get any closer to saying exactly what was wrong. he was pretty slick and sounded more motivational than instructional. he did plug the ffc's. i am a bit cynical. maybe some have been helped by him but i didn't get much new out of it.just my 2 cents worth.
