The following is taken from the section, "How should treatment be given", from the peer-reviewed medical-journal article, "The Many Faces of Cobalamin (Vitamin B12) Deficiency": [Start quote] For parenteral therapy in cases of megaloblastic anemia, it has been advised to administer 1000 mg hydroxocobalamin IM twice weekly for a period of 5 weeks, and the dose is reduced to 1000 mg IM every 2 months thereafter

Research Applications (laboratory / non-clinical research only) In vitro studies of copper peptide influence on fibroblast activity and collagen-related gene expression Animal model research into dermal matrix composition and connective tissue remodeling Preclinical investigation of copper-dependent antioxidant enzyme pathways, including superoxide dismutase activity Comparative research alongside other copper-binding peptides such as GHK-Cu in laboratory settings Cell culture studies examining peptide stability and copper ion delivery mechanisms Quality & Sourcing AHK-Cu 100mg peptide research material is synthesized to high purity standards and verified by HPLC (High-Performance Liquid Chromatography) analysis

Studies and research show that BPC-157 promotes healing through several pathways
Users maintaining excellent sun protection, adequate moisturization, healthy diet supporting collagen synthesis (adequate protein, vitamin C, copper from foods), sufficient sleep, stress management, and avoidance of collagen-damaging habits (smoking, excessive alcohol) preserve treatment gains better than users with suboptimal skincare and lifestyle creating ongoing skin stress overwhelming GHK-Cu induced improvements
