Peptide structure and stability What peptides are: Chains of amino acids Held together by peptide bonds Specific 3D structure required for function Fragile molecules compared to small molecule drugs Why peptides are unstable: Peptide bonds susceptible to hydrolysis (water breaks bonds) Oxidation damages certain amino acids Temperature accelerates degradation Light exposure causes photo-degradation pH changes denature structure Bacterial contamination introduces enzymes that break peptides Degradation mechanisms: Temperature's exponential effect: Every 10C temperature increase roughly doubles degradation rate Room temperature (25C): Rapid degradation (days) Refrigerated (2-8C): Slow degradation (weeks-months) Frozen (-20C): Very slow degradation (years) Ultra-frozen (-80C): Minimal degradation (5+ years) Learn peptide fundamentals at SeekPeptides - explore what are peptides , how peptides work , and getting started with peptides

When you are working with a potent GLP-1 receptor agonist like tirzepatide, those percentage differences in accuracy matter for consistent results

This increase in energy helps combat fatigue, making it easier to stay active and motivated to exercise, which, in turn, burns more calories
