TB-500 is a synthetic analog of Thymosin Beta-4 a naturally occurring protein involved in cell migration, cytoskeletal reorganization, and connective tissue repair
Western blot results showed that GHK-Cu significantly upregulated SIRT1 expression in the colon tissues of DSS-induced mice and MCECs in the co-culture system
It is also known that activation of cytoprotective transcription factor NRF2 (nuclear factor-erythroid 2-related factor 2) upregulates TRX and TRXR
Current evidence remains exploratory, with no approved human applications, positioning the neurological research surrounding BPC-157 and neural repair as preliminary but consistently documented across animal models
In contrast, GHK-Cu administered subcutaneously is released into the bloodstream instantly and in a controlled dose, which triggers more than 300 repair-related genes, helps to multiply fibroblast growth and contributes to the longevity of epidermal stem cells located in the basal layer
