The Bottom Line: A Sophisticated Tool GHK-Cu is a sophisticated biological signal that works best when: Sourced from reputable, verified pharmacies
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)
