This comparison does not assign a generated winner or score.
- Rest phase (1–3 hours post lights-off)
- Peak GH pulse, elevated IGF-1
- Low (cortisol nadir, melatonin high)
- Elevated (HIF-1alpha peak)
- High (anabolic metabolism active)
- 100% baseline
- Optimal window. TB-500 synergizes with endogenous growth factors and low inflammation. Maximizes angiogenesis and fibroblast recruitment.
- Active phase (mid-waking cycle)
- Suppressed GH, low IGF-1
- Elevated (IL-6 and TNF-alpha peak)
- Low (VEGF at circadian nadir)
- Moderate (catabolic metabolism)
- 60–70% of rest-phase efficacy
- Suboptimal. Peptide functions but lacks hormonal amplification. Inflammatory tone diverts TB-500 signaling to damage control rather than tissue building.
- Sleep-deprived state (chronic restriction)
- GH pulse blunted by 50–70%
- Chronically elevated (IL-6 up 40–100%)
- Dysregulated (circadian rhythm disrupted)
- Low (20–30% reduction in ATP)
- 50–65% of sleep-adequate baseline
- Poor context. TB-500 bioavailability unchanged, but cellular readiness for anabolic signaling is compromised. Oxidative stress and ATP depletion limit actin dynamics.
- Immediate post-exercise (active phase)
- Transiently elevated GH, cortisol high
- Acutely elevated (exercise-induced IL-6)
- Transiently elevated (hypoxia-driven)
- Depleted (glycogen low, lactate high)
- 70–80% of rest-phase efficacy
- Mixed outcome. GH and VEGF transiently favor TB-500 action, but cortisol and ATP depletion limit sustained anabolic effect. Better than baseline active-phase dosing but inferior to rest-phase.
