btw, they do have Pantethine in several patches but you get a lot of other stuff with it.

Do you have a link? I would be forever indebted.

Going to try to have the blood work added to the other tests for my current problem. It would be nice to get the metabolomics for both the oral and patch to determine the GI issues related to each. We know Pantethine converts (mostly) in the intestinal lumina to cysteamine and pantothenic acid (via pantetheine hydrolase). A patch would bypass that process and lower the dosing.

Actually, after looking at it..the patches have

Pantothenic Acid which is not exactly what you wanted
