Additionally, older adults have a harder time absorbing vitamin B12
Combining both peptides ensures comprehensive coverage regardless of the specific tissue composition of injured areas

meanwhile, hypoxia-induced pulmonary vasoconstriction raises pulmonary artery pressure, and the kidneys respond by secreting erythropoietin to stimulate erythropoiesis in bone marrow, further augmenting red blood cell numbers ( 1.2.3 Increased blood viscosity and hemodynamic changes Due to the increased number of red blood cells and heightened hemoglobin concentrations, blood viscosity significantly rises under high-altitude conditions, presenting as increased resistance to blood flow, exacerbating the hearts workload, and potentially affecting microcirculation and overall circulatory efficiency ( 1.2.4 Tissue damage and pathological processes Long-term or severe hypoxia can trigger various tissue damages and pathological processes: Cellular Oxidative Stress: Cellular oxidative stress is a pathophysiological state in which the balance between intracellular oxidation and antioxidant action is upset in favor of the oxidative process, resulting in the abnormal accumulation of reactive oxygen species (ROS) such as superoxide anions (O2 ), hydrogen peroxide (HO), hydroxyl radicals (OH), etc

This aligns with epidemiological evidence showing that higher BMI predicts poorer quality of life and greater mood disturbance severity (Rindler et al., 2023)
Its chemical stability and non-toxic copper delivery capacity further underscore its utility as a molecular tool for investigating gene expression, tissue regeneration, and copper-mediated biochemical processes (Pickart, Vasquez-Soltero, and Margolina 2012)
The combination eliminates the need for two separate injections, reduces total injection volume, and ensures consistent dosing ratios optimized for synergistic effects
