This was from a 1991 paper. They didn't measure Hb/HCT and it probably would not have been long enough to see differing effects (both would have showed some increase). From this data set, 100 mg/wk had few adverse affects relative to SHBG, Apo A-I (HDL) or prolactin, not on this graphic (both 100 and 300 mg/wk). The ND clearly does not aromatize to the same extent as T, probably about 25% if that so if ND was exchanged in part with TC/TE, you would expect a decrease in E2.
In a male HIV study, 600 mg/wk of ND increased Hb about 1.0 g/dl in 12 weeks. Compared to Bhasin's study in younger men (20 weeks), 600 mg/wk of T increased Hb about the same 1.4 g/dl, in older men almost double that, so an age factor that most of us older guys know already based on personal experiences.
So in the end, adding a low dose of ND <100 mg/wk shouldn't blow up the Hb much more than adding more T, of course responses are individual and a more frequent phlebo schedule might be needed. If the reduction in joint pain is significant than the lower dose is probably worth it and shouldn't have any significant effects on SHBG, E2, HDL or prolactin.
