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.
