Last year I experimented with LDN for my RA (Rheumatoid Arthritis) in place of enbrel and methotrexate. I gave it 13 months, but failed as an alternative RA drug option. During that period I gave blood 3 times when my Hct went over 52. In the early spring, I went back on Enbrel and Methotrexate, now I should not have to worry any more. TRT raises H&H, and the 2 drugs I am using for my RA are lowering my H&H. Last week my Hgb was 14.8 g/dl and Hct was 45.2 %. In a way TRT is a good adjunct to my RA therapy, in the past my H&H was quite low, currently they are, close to optimal.
