My guess is that it must be different. The Intral person I discussed this with told me that the VHC was too dense to go through a peg and would cause problems. She also said we should NOT thin it with water-don't know why, but their nutritionist is supposed to call me tomorrow. There is so much info AND mis-info out there, it takes alot of trial and error in my experience. I will post what I find out tomorrow. But extra calories would be great for us, so we are following through. Amy
