Additional Monitoring May Be Considered In: Higher-frequency regenerative research protocols Long-duration experimental protocols Multiple concurrent regenerative or metabolic-support compounds Significant peptide-sensitivity research models Liver-function or copper-metabolism-related investigations due to the inclusion of GHK-Cu Avoid or Carefully Evaluate In Research Models With: Known hypersensitivity to peptide compounds Active severe systemic illness Severe uncontrolled cardiovascular, metabolic, or neurological conditions Active or suspected malignancy-related, tumor-related, or abnormal proliferative conditions Pregnancy or breastfeeding contexts Additional Research Considerations Because Glow Blend contains GHK-Cu, prolonged or higher-frequency research exposure may influence copper and zinc balance in some research settings
