Skeletal muscle dysfunction is an important co‐morbidity in patients with chronic obstructive pulmonary disease (COPD) and is significantly associated with increased mortality. Oxidative stress has been demonstrated an important trigger for COPD‐related skeletal muscle dysfunction. Glycine‐histidine‐lysine (GHK) is an active tripeptide, which is a normal component of human plasma, saliva, and urine; promotes tissue regeneration; and acts as an anti‐inflammatory and antioxidant properties. The purpose of this study was to determine whether GHK is involved in COPD‐related skeletal muscle dysfunction.
