BPC-157 Research Hormonal Cycle: Comparison of Follicular vs Luteal Response
Follicular (Days 1–14) Estrogen (50–300 pg/mL) Elevated 30–50% above baseline Low. M2 macrophage dominance Amplified via increased VEGF receptor density Acute injury models, tendon repair studies, maximum angiogenesis protocols Luteal (Days 15–28) Progesterone
This comparison does not assign a generated winner or score.
- Follicular (Days 1–14)
- Estrogen (50–300 pg/mL)
- Elevated 30–50% above baseline
- Low. M2 macrophage dominance
- Amplified via increased VEGF receptor density
- Acute injury models, tendon repair studies, maximum angiogenesis protocols
- Luteal (Days 15–28)
- Progesterone (10–20 ng/mL)
- Reduced 15–25% below peak
- Elevated. M1 macrophage dominance, sustained TNF-alpha
- Attenuated due to prolonged inflammatory phase
- Chronic inflammation models, immune modulation studies, worst-case healing scenarios
- Ovulatory (Days 12–16)
- Estrogen peak + LH surge
- Peak collagen deposition
- Transitional. Rapid immune cell turnover
- Variable. Angiogenic surge followed by inflammatory rebound
- Avoid for outcome consistency. High hormonal volatility
