Better insulin function means more efficient nutrient partitioning, where calories are more likely to support muscle maintenance rather than fat storage
Teams working on nanoparticle carriers, chemical penetration enhancers, and microneedle-assisted delivery are making genuine progress on exactly this problem
Both should stay in carry-on bags and in their original containers for easy identification
Delivering a peptide by mouth is genuinely hard, which is the whole reason absorption-enhancer technology exists
