- Semax and GHK-Cu are both studied for neuroprotective activity, but they access CNS biology through entirely distinct receptor-effector systems — Semax through neurotrophic growth factor signalling (BDNF-TrkB-PI3K-Akt-CREB), GHK-Cu through redox transcription (Nrf2-ARE-HO-1). Understanding when each is appropriate, what controls are needed, and how they interact mechanistically is essential for valid CNS injury research design. This post provides that mechanistic head-to-head. It is distinct from the BPC-157 vs Semax comparison (ID 77392, vascular/BBB versus neurotrophic framing), the Semax pillar guide, and the GHK-Cu pillar guide.
