- Metabolic Endpoint Clarity
- Clean ERRγ-driven signal; mitochondrial biogenesis effects isolated
- Overlapping lipolysis and thermogenesis; unclear attribution of observed effects
- Minor residual adenosine receptor effects; 90%+ signal clarity restored
- Controlled timing preserves data integrity. Uncontrolled timing compromises endpoint attribution
- Insulin Sensitivity Measurements
- Reflects peptide's impact on glucose handling via enhanced oxidative capacity
- Caffeine reduces insulin sensitivity 12–18%; masks or reverses peptide's glucose improvements
- Caffeine effects dissipated; insulin measurements reflect peptide mechanism accurately
- Eight-hour washout eliminates caffeine's confounding effect on glucose tolerance testing
- Substrate Oxidation Data
- Increased fatty acid oxidation from mitochondrial upregulation
- Caffeine-induced lipolysis artificially inflates fat oxidation rates independent of mitochondrial changes
- Lipolytic spike resolved; oxidation data reflects mitochondrial capacity, not acute catecholamine release
- Separation required for accurate respiratory quotient and substrate utilisation analysis
- Reproducibility Across Days
- Consistent effects when dosed at same time daily
- High day-to-day variance if caffeine intake timing fluctuates across protocol days
- Reproducible results when caffeine restriction is standardised
- Variance reduction is essential for multi-day protocols and dose-response studies
