Tracking weekly fasting glucose + insulin on a CJC-NoDAC/Ipa/tesa stack (100mcg/200mcg/1mg). 10 weeks in. Same meter (Contour Next), same lab for insulin (Quest), draws Tuesday AM fasted 12h, same restaurant for coffee the day before (kidding).

Glucose (mg/dL, fingerstick mean of 3):

  • Wk 0: 84
  • Wk 2: 86
  • Wk 4: 89
  • Wk 6: 91
  • Wk 8: 93
  • Wk 10: 92

Insulin (mIU/L, lab):

  • Wk 0: 5.8
  • Wk 4: 7.1
  • Wk 8: 8.9
  • Wk 10: 9.4

HOMA-IR: 1.20 -> 1.47 -> 2.04 -> 2.14.

That's not catastrophic but it's the 'GH stack insulin creep' I keep reading about. How much of this do I eat before cutting a dose?

Agreed with above. My additional take: add berberine 500mg tid if diet is dialed. Cheap insurance, real effect on fasting insulin (~15-20% drop in most responders).

My heuristic: HOMA-IR < 1.5 = fine, 1.5-2.0 = monitor, 2.0-2.5 = pull back one lever (drop dose, cut days, or swap tesa out), >2.5 = hard stop on stack and reassess. You're at the 'pull back one lever' threshold.

Easiest lever here is probably cutting tesa to 1mg 5x/wk from 1mg daily, or dropping CJC to 4x/wk.

Your glucose trend looks close to maxed-out at 92-93. Likely to stabilize. Insulin is the one you want to watch โ€” it's still climbing.

Also โ€” carb timing. If you're eating most carbs in the evening the fasting insulin takes longer to drop overnight. Shifting carbs earlier in the day can reduce fasting insulin 10-20% independent of drug changes.

Are you doing AM dosing? Some people see meaningfully less insulin creep shifting their GH secretagogues to post-workout + bedtime only, skipping the AM pulse.

AM + PM currently. Going to try bedtime-only for 2 weeks and retest.

Don't forget HbA1c is the integrator of record. Weekly fasting glucose + insulin is a great early warning system but a1c at week 12 is the 'is this a real metabolic issue' datapoint.

a1c baseline 5.1, pulling it at week 12 (next week). Will update.
