I am actually new here to the boards and the forum world, but would like to contribute and learn at the same time. From what I understand is that people here suspend their orals in aqueous solutions. I make my own tablets and follow USP standards because excipients used in a formulation directly effect absorption of the material and offer some protection before it enters the small intestines. I know this is about getting your products to suspend in a solution and taste good, but I am wondering analytically how do you know how many mgs are being absorbed in the body? Maybe somebody can help me understand that?
