Very Very confusing. They pick and chose a few things like Hiv and Cancer and say they're knockouts yet they list a ton of diseases and don't say wether they're knockouts if they've been at the same levels for 2 yrs.All I've ever talked to are customer service reps.I don't even think they have a marketing dept. They know the app is super confusing and tell you"if unsure write the GI".Its amazing that insulin is a knockout if not the same levels for 2 yrs. That's were the contesting of claims will come.Tons of people have a change of dosages over a 2 yr people. I'm staying away from the level . There's too many co's that will take many of these ailments level.
