Glycyl-L-histidyl-L-lysine (GHK) is a nontoxic tripeptide involved in the process of healing and regeneration as a natural product
(2024) employed a maternal immune activation (MIA) mouse model, induced by lipopolysaccharides (LPS) administration during pregnancy, which led to autism-like behaviors in the offspring

BPC-157: The Angiogenic Healer BPC-157's healing effects center on blood vessel formation and cytoprotection: VEGF Upregulation: Increases vascular endothelial growth factor, promoting new blood vessel formation to injured tissues (PMID: 27847966, PMID: 40789979) Nitric Oxide System: Modulates NO pathways, protecting tissues from oxidative damage and improving blood flow (PMID: 31158953) Growth Factor Pathways: Interacts with and functionally engages growth-factordependent cytoprotective and regenerative pathways, producing growth-factorlike effects (PMID: 11718984, PMID: 40789979) Cytoprotective: Protects cells from various toxic insults including NSAIDs, alcohol, and ischemia (PMID: 31158953) Nerve Healing: BPC-157 indirectly modulates GABAergic inhibitory control, supporting nerve regeneration (PMID: 15840402) TB-500: The Cell Migration Facilitator TB-500 is a synthetic peptide designed to mimic Thymosin -4, which is well-established in actin sequestration, cell migration, wound repair, and anti-inflammatory signaling

Both are excellent choices for sensitive skin types or first-time users of face tan removal soap
