Unfortunately readalot is the Quanon of Meso.Readalot, if you go to the analytical testing subforum here on meso, there are plenty of lab tests of large, massive pharmaceutical corporations producing meds such as ibuprofen that are off by as much as +/- 10% or a tiny bit more. A +/- 10% margin of error is a very real phenomenon for us as the consumer when we purchase drugs at the store....it just is readalot. You are wrong about the +/- 5% figure.
