TB-500: Mobilising the Repair Response
TB-500's wound healing capabilities stem from its role in the early, critical phases of tissue repair:
Cell Migration (Phase 1): TB-500 binds to G-actin monomers, promoting actin polymerisation and enabling repair cells — fibroblasts, endothelial cells, keratinocytes — to physically migrate to the wound site. This is often the rate-limiting step in healing.
Angiogenesis (Phase 2): TB-500 promotes endothelial cell migration and tube formation, creating new blood vessels that supply the wound bed with oxygen, nutrients, and immune cells. Inadequate blood supply is one of the most common causes of poor wound healing.
Inflammation Control: TB-500 modulates inflammatory cytokines, reducing excessive inflammation that can cause tissue damage and delay healing. It preserves the beneficial inflammatory signals needed to initiate repair whilst dampening the destructive chronic inflammation.
Cardiovascular Relevance: TB-500's wound healing properties extend to cardiac tissue, where it has shown efficacy in heart tissue regeneration models — a unique characteristic among wound healing peptides.
GHK-Cu: Rebuilding Tissue Structure
GHK-Cu's wound healing contribution comes during the later remodelling and structural restoration phases:
Collagen Deposition: GHK-Cu directly stimulates fibroblasts to produce collagen types I and III — the primary structural proteins in healing tissue. Proper collagen deposition is essential for wound strength and prevents wound reopening.
Scar Remodelling: GHK-Cu promotes organised collagen deposition and tissue remodelling, which produces better cosmetic outcomes. Disorganised collagen leads to visible, raised scarring; organised collagen leads to flatter, less visible scars.
Copper Delivery: As a copper-binding peptide, GHK-Cu delivers copper ions to wound sites where they serve as essential cofactors for lysyl oxidase (collagen crosslinking), superoxide dismutase (antioxidant protection), and cytochrome c oxidase (cellular energy production).
GAG Production: GHK-Cu stimulates production of glycosaminoglycans including hyaluronic acid, which provides the hydrated matrix necessary for cell migration and new tissue formation during the proliferative phase.
TB-500 + GHK-Cu: Covering the Full Healing Timeline
The combination of TB-500 and GHK-Cu addresses wound healing across its entire timeline:
Phase 1 — Inflammation (TB-500): TB-500 modulates the initial inflammatory response, preventing excessive damage whilst maintaining repair signals.
Phase 2 — Migration & Proliferation (TB-500 + GHK-Cu): TB-500 drives cell migration to the wound site. GHK-Cu begins supporting GAG production for the extracellular matrix. Both promote angiogenesis through different mechanisms.
Phase 3 — Remodelling (GHK-Cu): GHK-Cu takes the lead, stimulating organised collagen deposition, elastin production, and tissue remodelling for optimal wound strength and cosmetic outcome.
Research Protocol: TB-500 is often emphasised in early weeks for migration and inflammation control, with GHK-Cu emphasis increasing as the protocol progresses into the remodelling phase. Both can be administered concurrently throughout.
