GHK

GHK-Basic (without copper) is less commonly used in research protocols compared to GHK-Cu. When studied, it is typically used at nanomolar concentrations in cell culture. Subcutaneous injection protocols are not well-established for the copper-free form. GHK-Basic is the foundational tripeptide that forms GHK-Cu when complexed with copper(II) ions.

Modulates the expression of a large number of human genes involved in tissue remodeling, antioxidant defense, anti-inflammation, and nervous system support. Gene expression analyses show influence on transcriptional networks for cellular migration, ECM turnover, and redox balance.

Modulates integrin signaling pathways involved in cell adhesion, migration, and extracellular matrix interactions.

Regulates transforming growth factor-beta signaling, influencing tissue repair, collagen synthesis, and inflammatory responses.

Suppresses pro-inflammatory cytokines and activates antioxidant response elements, reducing oxidative stress at the cellular level.

Demonstrated ability to improve tissue repair in skin, lung connective tissue, bone, liver, and stomach lining.

Stimulates synthesis of collagen and glycosaminoglycans in skin fibroblasts at picomolar to nanomolar concentrations.

Reduces levels of pro-inflammatory cytokines and promotes resolution of inflammation.

Acts as an endogenous antioxidant, potentially diminishing hydroxyl and peroxyl radicals in living organisms.

Natural modulator of multiple cellular pathways in skin regeneration, supporting dermal repair and anti-aging effects.
