That reframing is the part I needed.

From the other side of the consultation, briefly.

PSA: get baseline labs BEFORE starting baseline bloodwork therapy. You need a "before" picture to measure progress. My recommended pre-treatment panel:

  1. CMP + A1C + fasting insulin
  2. Complete lipid panel with particle count if possible
  3. hsCRP, ferritin, B12, vitamin D
  4. Thyroid panel (TSH + free T4)
  5. CBC with differential
  6. Liver panel (ALT, AST, GGT)
  7. DEXA scan or body composition

Total cost at Quest without insurance: ~$200. Worth every penny for the data.

Shot day Thursday report relevant to baseline bloodwork: Week 16.

Worth saying that the confident version of this is more useful to the person writing it than to the person reading it.

The figures, for anyone assembling their own picture. If you are comparing against somebody else’s result, check that you are comparing the same measurement taken the same way. Most of the apparent contradictions in these threads dissolve at that step.
