Increased T Level Despite Lower Dose

Both labs were drawn 30 hours post-injection. I inject twice per week.

The first picture is from September. My dose was 110mg/week. I wanted to be in the 700-800 range, so I lowered my dose to 92mg/week. The second picture shows my labs from three months later. Any idea how this increase could happen? Lab error? Should I go back and ask for the MS test instead of IA?

The only difference in my life is that I started taking b12 every day about 3 weeks ago. Surely that couldn’t make that big of a difference?

I’m just unsure whether to lower my dose any further, get follow up labs, or just do nothing. All of my other bloodwork is fine (no high hematocrit or anything).
