Their biological activity depends on maintaining the precise three-dimensional conformation of their amino acid chain, along with the integrity of any chemical modifications — such as the C20 fatty acid moiety on retatrutide and tirzepatide, or the copper chelation complex in GHK-Cu — that are part of their functional design. Heat, moisture, light, oxygen exposure, and mechanical stress all attack these structures through distinct degradation pathways. Thermal degradation accelerates peptide bond hydrolysis, breaking the amino acid chain at vulnerable points and producing truncated fragments - [GHK-Cu Peptide: What Researchers Need to Know About the Glow 70mg Formula](https://evolvelabsuk.co.uk/2026/07/09/ghk-cu-glow-70mg/): GHK-Cu is a naturally occurring copper-binding tripeptide with a wide-ranging research profile covering collagen synthesis, wound healing, and gene expression modulation.
