    6/ How Do we Measure Success:

    I’ll perform the following tests, implement my microdosing protocol, then retest after 12 weeks to determine success of the intervention.

    Metabolic Health:

    + Continuous glucose monitoring: Mean glucose, variability, peaks.

    + Insulin, HbA1c,…

    4/ My Microdosing Protocol

    To evaluate the potential benefits I will start a 12 week trial of the GLP-1/GIP RA Tirzepatide (Commercial name: Munjaro for diabetes, Zepbound for weight loss).

    I'll start with a weekly dose of 0.5 mg, that is 1/2 the typical microdose, and 1/5 of…

    2/ Metabolic and Longevity Benefits

    Metabolic Optimization: Less glucose spikes, lower insulin levels, and thus reduced advanced glycation end-products (AGEs) (4, 5).

    Anti-Inflammatory Effects: Systemic inflammation reduction by decreasing pro-inflammatory cytokines like TNF-α…
