[educational] GHK-Cu promotes angiogenesis via VEGF/FGF-2 upregulation (supplying skin/hair/tissue with nutrients for repair) — a shared mechanism with BPC-157, and a reason for the same cancer-caution framing. — GHK-Cu deep dive
[educational] TB4 promotes angiogenesis via actin-driven endothelial migration — less potent than BPC-157’s NO/VEGF route, but complementary (why the two are combined for major injuries); also a shared cancer-caution mechanism. — TB500 deep dive
