This comparison does not assign a generated winner or score.
- Primary Endpoint
- Inflammation resolution, tissue repair velocity
- Capillary density, mitochondrial enzyme activity, lactate clearance
- Endurance models require multi-week observation windows. Acute endpoints don't capture adaptation
- Washout Period
- 24–48 hours sufficient if measuring wound closure
- 72–96 hours minimum for acute performance; 4–6 weeks for structural endpoints
- Plasma half-life doesn't predict tissue-level mechanism persistence
- Dose Range
- 200–500 mcg/kg shows consistent response
- 200–300 mcg/kg likely sufficient; higher doses don't proportionally increase angiogenesis
- Dose-response plateaus at receptor saturation. More isn't better
- Subject Variability
- Lower. Injury severity standardizable
- Higher. Baseline training status significantly affects response
- Stratify by VO2 max or training history to reduce variance
- Mechanism Timeline
- Days to 2 weeks
- Weeks to months. Signaling initiates during dosing, remodeling occurs post-cessation
- Don't measure structural adaptation until 4+ weeks after final dose
- Storage Sensitivity
- Moderate. Single-use reconstitution common
- High. Multi-month studies require staggered reconstitution and cold chain monitoring
- Temperature excursion ruins an entire batch. Log fridge temps daily
