Both peptides appear in regeneration and recovery research. Investigators weighing them are typically comparing systemic soft-tissue repair (TB-500, injectable) against topical skin and follicle work (GHK-Cu, topical or subcutaneous).
TB-500 research centers on muscle, tendon, and cardiac repair via actin sequestration. GHK-Cu research centers on dermal collagen, follicle signaling, and surface wound healing. Different tissues, different routes — not substitutes.
GHK-Cu
Copper-bound tripeptide for skin + hair
TB-500
Actin-binding healing fragment
About GHK-Cu
The copper-bound form of GHK, extensively studied for skin renewal, wound healing, and hair follicle signaling.
About TB-500
TB-500 is a synthetic fragment of the naturally-occurring thymosin beta-4 peptide, studied in animal models for soft-tissue repair and inflammation modulation.
