- Glutathione (GSH)
- Intracellular antioxidant; substrate for GPx and GST enzymes
- Cytoplasm, mitochondria, organelles
- IV, liposomal oral, sublingual
- GSH:GSSG ratio, MDA, protein carbonyls, oxidative stress markers
- Best for oxidative stress protocols. Does not bind receptors or trigger signaling cascades
- BPC-157
- Receptor-mediated signaling; binds VEGFR2, integrin receptors
- Endothelial cells, fibroblasts, epithelial tissue
- Subcutaneous, intramuscular
- VEGF expression, wound closure rate, collagen deposition, angiogenesis markers
- Mechanistically distinct from glutathione. Acts on tissue repair through receptor pathways
- TB-500 (Thymosin Beta-4)
- Actin-binding protein; modulates cytoskeletal dynamics and cell migration
- Cytoskeleton, injured tissue sites
- Subcutaneous
- Cell migration assays, tissue regeneration histology, actin polymerization
- Does not address oxidative stress. Focuses on structural repair and cell motility
- Epithalon (Epitalon)
- Telomerase activator; pineal peptide regulator
- Pineal gland, telomeres
- Subcutaneous, IV
- Telomere length, melatonin secretion, circadian regulation markers
- Unique mechanism unrelated to antioxidant or wound repair pathways
- GHK-Cu (Copper Peptide)
- Copper-binding tripeptide; stimulates collagen and glycosaminoglycan synthesis
- Fibroblasts, extracellular matrix
- Topical, subcutaneous
- Collagen I/III ratio, elastin content, dermal thickness, TGF-beta expression
- Structural repair focus. Copper-dependent mechanism distinct from glutathione's redox function
