I had blood work done and test came back 387. This was done by endo. 4 weeks later I had an appointment with my regular dr and thought I would have it checked again. Only difference I took chrysin, which I happened to find in my cabinet, the blood work was send to different labs. The second test came back 518. Could this have been due to the Chrysin or just the difference in the two labs? By the way I am on 200mg of test every two weeks TRT.
