Hi all, Got the results back from MSU today. IAA was negative (8), but IGF-1 was way over the normal range. His SpecFPL was 8 which is also high. I have been doing the TR Protocol and now know why he hasn't moved one bit from the reds. Does Lev work better for our Acro cats? What is the next step the vet will recommend, an ultrasound? What else can I do? I have read about using R? This is depressing. Thanks.
