TB-500 Research Menstrual Cycle Considerations: Comparison
Follicular (Days 1–14) Estrogen rising High. Estrogen upregulates actin turnover and VEGF expression Anabolic, regenerative, angiogenesis studies Low (CV <20%) Optimal window for measurable tissue repair endpoints Ovulatory (Days 13–15) Estrogen peak, LH surge
This comparison does not assign a generated winner or score.
- Follicular (Days 1–14)
- Estrogen rising
- High. Estrogen upregulates actin turnover and VEGF expression
- Anabolic, regenerative, angiogenesis studies
- Low (CV <20%)
- Optimal window for measurable tissue repair endpoints
- Ovulatory (Days 13–15)
- Estrogen peak, LH surge
- Moderate. Transient inflammatory surge may interfere
- Avoid dosing during this 48-hour window
- High (CV >35%)
- Unpredictable due to acute inflammatory signaling
- Luteal (Days 15–28)
- Progesterone dominant
- Low. Progesterone suppresses MMP activity and VEGF
- Anti-fibrotic, scar resolution, inflammatory modulation
- Moderate (CV 25–30%)
- Secondary window for non-anabolic endpoints
- Anovulatory Cycle
- Variable, often estrogen-only
- Unpredictable. Lacks progesterone surge
- Exclude from analysis entirely
- Extremely high (CV >50%)
- Introduces uncontrolled confounding. Do not include in results
