Heat accelerates all degradation pathways, but with GHK-Cu it also increases the rate of copper-catalyzed oxidation
Nevertheless, here is the general framework: 1

When to extend timeline Consider using beyond 30 days when: Peptide is very expensive (TB-500, pharmaceutical GLP-1s) You're close to finishing vial (only 2-3 doses remain) Peptide appears perfect (clear, no smell, stored optimally) You're using for non-critical purpose (anti-aging vs acute injury) Financial hardship makes wasting difficult Maximum extension: 45 days for most stable peptides (BPC-157, TB-500, semaglutide)
Chronic Fatigue: Persistent fatigue caused by nutrient deficiencies or electrolyte imbalances may benefit from IV drips
You may notice a little bruising later
