Research Comparison
TB-500 vs GHK-Cu: Regenerative Peptide Research Comparison
TB-500 and GHK-Cu are both studied in the context of tissue remodeling but have fundamentally different molecular structures. TB-500 is a 43-amino-acid actin-binding peptide, while GHK-Cu is a copper-complexed tripeptide.
Structure and Mechanism
TB-500 (MW 4921 Da) operates through G-actin sequestering via the LKKTET domain. Malinda et al. (1999, PMID: 10469335) observed 42-61% increases in re-epithelialization in wound models.
GHK-Cu (MW 403.93 Da) is copper-dependent and has been studied for gene expression modulation. Pickart & Margolina (2018, PMID: 29986520) reviewed evidence that it modulates expression of over 4,000 human genes in cell culture models.
