Hi @mayblin - Yeah, I have been pretty happy after figuring out they used L2-L5 instead of L1-L4. So I don't have an initial L1 BMD, but looking at the other scores, it looks like I have gained about 15% in the spine, 9% in the femoral neck, and 5% in the total hip. Attached is my spreadsheet for tracking improvements in BMD. One other note, I also was given DXA scores compared to an average male, which might make sense on the surface, but all of the fracture models are based on women, so for fracture risk and T-Score, men are supposed to use the women's scale. You'll see that called out on my spreadsheet.

One more thing I'm finding. Since the vertebrae are irregular in shape, the numbers bounce around a bit. For that reason, it is probably best to just look at the average L1-L4 number. You can see that after about 10 months on Prolia, I had two vertebrae with no gain and two gaining 8%. I know that is not reality so the average is probably the best number to look at.

So yeah, feeling pretty good right now and so far so good. I make sure to take in about 1500mg of calcium per day because I still have hypercalciuria to the tune of about 350mg.
