Thank you so much for your reply! Yes, I am definitely struggling with my GI and support, I wish that I had been warned to not change my habits after the biopsy and posting of results as I then would have continued to eat gluten and would have no need for a trial. But I unfortunately need an official diagnosis as I cannot get accommodations in college without one, so I am thinking to do the gluten trial! Do you think 2 weeks will be long enough, by the time I begin I will only have been gluten free for about 2 months. I'm considering looking for another GI or a celiac specialist like you mentioned, that could really help! Thank you for your response and advise, hopefully I won't feel too horrible during the trial (although it is hard to imagine going back to gluten after feeling good for the first time in months without it), but I hope it will work out! Thanks again

No, I haven't tried Gliadin X, although @Scott Adams might be able to discuss his experiences.   I think it's a bad idea to take GliadinX during your gluten challenge.  You won't mount a strong enough autoimmune response.  

Yes, it is possible to have Celiac Disease without lymphocytosis.  

By the way, this new article is very relevant to this thread:  

The FDA doesn't regulate nutraceuticals like this. The AN-PEP enzyme has been used for decades in commercial beer brewing as a clarifying agent, and is no longer patentable, thus no pharmaceutical companies are interested in it specifically, although there are companies that are trying to develop their own version of it that can be patented.
